Aye up chaps – been a while since I updated the thread so here are a few more installments
!
I fitted the hard top late last year (2009) in order to free up some space in the garage but having it in place didn’t leave me with much room in which to fit the rollbar. The hardtop’s too big/heavy for one person to remove so I was stuck with it! I already had the passenger’s seat out of the car so decided to take the drivers seat out as well to give me more room – it would have had to come out soon enough anyway as I have some MX5 seats that I want to fit. The bar went in the car no problem & using some pointers I'd printed off the Scimweb forum (a mine of information) I started the job! The first mistake I made was that I didn't mark where the feet of the bar went when the carpet was in place. So once I'd fitted & bolted the bar in place without the carpet in the car I realised that it'd all have to come out again so that I could refit/mark/cut the carpet!! Did I feel a numpty? Yes I did!
I have a non-galvanised car so I wasn't sure whether the captive nuts - as fitted to some (all?) galvanised cars - for the roll bar feet bolts would be there or not. It turns out that they aren't fitted to my car so I had to drill some 10mm holes to accept the bolts that had been sent with the roll bar. Unfortunately these bolts weren't long enough so I had to make a quick trip to Screwfix (there's a branch close to our house) to get some long enough bolts & also some nyloc nuts. This is turning into a longwinded way of saying that the bar fits fine & feels reassuringly solid when it's all bolted up. It feels as if it should increase the strength of the car quite a lot even though it is only bolted in place. I'm told that welding it in position would be better but I'm not sure how I'd do this given that there's a layer of glass fibre between the rollover bar feet & the actual chassis & I'm not taking the car to bits any more than it is already! The bar is also held in place by three M8 bolts at the B-post so it’s held in position by 12 bolts (6 per side) in total. It feels totally solid & should increase the strength/rigidity of the car quite a bit. I have been told that the strength of the actual bar can be increased by welding a diagonal bar across it but I’m not sure this is really necessary.
Anyway here are a few pictures of the job – the last one shows the finished installation.
The first pic shows the roll bar foot & the three M10 bolts that hold it in position. I’ve used thick washers/spreader plates behind to secure them. Access was a complete pig & I had to remove the rear shock absorbers to give me more room – even then the rear suspension arms got in the way & I ended up using just about every extension I had in my socket set to reach the nuts. There’s no way I’m removing the roll bar now & I’m glad that fitting it is finished!!
This pic shows the roll bar in position - all holes drilled & partly bolted in. I then realised that it'd have to come out again so that I could fit/mark/cut the carpet.
This photo shows the clearance between the roll bar & inside of the hard top (it also shows that my hard top needs retrimming). Clearance with the hard top fitted is fine, so it should be ok with the soft top fitted, but I'll just have to wait & see. The soft top's pretty worn out & could really do with replacing so I'll probably end up using the car with the hard top fitted most of the time.
And here we have the finished installation - carpet fitted & cut, roll bar in position & all bolts tightened up. I like the way it looks & it feels proper, & I mean PROPER, solid & I'm chuffed with it. I'm not sure I'd want to do the job again anytime soon though!!
Opinions welcome as always.
I spent Saturday hack sawing, drilling, tapping, sweating, straining & swearing as I adapted the Reliant seat runners to fit a pair of MX5 seats I’d bought a few months ago. I'd already fitted the passenger’s seat once but removed it so that I could copy the adapters I'd made for the seat runners. I made the adapters out of some 10mm iron plate I had in stock – my idea being to bolt these plates to MX5 seat bases using the M8 holes already tapped into them, & then bolt the Reliant runners onto the plates into which I’d tapped another M8 hole. I didn't take any photo's of the adaptors I'm afraid (sorry about that) but they seem to do the job well enough. They were fiddly & time consuming to make though - the worst part being hack sawing through the 10mm plate! Both seats feel very secure & still move forwards & backwards (the drivers side a little reluctantly). The seats themselves are much comfier & more supportive than the originals (which were knackered) but also felt overstuffed, almost as if you were sitting on top of them rather than in them (if that makes any sense?). So I removed the seats & covers & attacked the seat foam with an electric carving knife (as you do!) to try & reduce the height of the seat cushion. Again it seems to have worked well & both seats (the drivers side especially) feel more “buckety” whilst still being comfortable. The main problem is that the seats sit a bit higher than the originals, this isn’t really a problem for me & Gillian as we’re both 5’7”ish but it probably will be a problem for anyone much taller than us. I can see me getting the seat rails lowered at some stage in the future which means doing a bit of cutting & welding & then getting the floor re-fibre glassed! It’s not a huge job (apparently), & plenty of people have already done it, but it’s not really something I want to start right now.
So that's the interior more or less sorted, next on the agenda is to try & get the engine running. I need to pull it out again so that I can fit a new clutch release bearing - I should have fitted one when the engine was out but, like a plonker, I forgot! The lack of a sump is still a problem but I’m hoping that it’ll be sorted soon! Then I'm probably going to have to leave the car for a bit until I can get the funds together for a fuel pump, carb(s)/manifold, megajolt ecu, starter motor, alternator mount & alternator, exhaust etc etc etc!
I'm getting married at the end of July, and then I’m off on honeymoon for 2 weeks, so it looks as if life will get in the way of the project for a while.
Anyway here are a couple of not very good pics of the seats installed.
Ta for all your support & I'll update the thread when I've got more to say.
