Update: Had a little time tonight to tinker with the 126.
Engine from 122 is ready to drop into the 126. As far as I can tell, the wiring harness on the 126 seems to be intact and OK. I've read the 1x5/6 wires can be problematic with age - we'll see.
Need to replace the clutch teaser spring - which I have. Question is - when you drive out the roll pins, do you block-up the end of the drive shaft with something like a piece of 2 x 4 or just bang away and drive the pins out?
Also managed to loose one of my new anti-rattle clutch springs...
Getting close with this 126 for a test drive to see what I've got.
Thanks!
Bill
