the guy in the usa has done 35000 miles with no problems, I have an oil pressure gauge and the pressure is better than standard 🙂
the bearings require a serious blow to move a mm, so if you mark up the 'drift' it's very easy to knock them in 7.5mm (well ok it's hard work knocking them in, but you can be very accurate)
I can do an exchange for your 'sawn off ends' with some machined 'idler ends' if you want dunno..
only takes a lathe to clean them up 🙂
