Hello Fred,
You need an adaptor plate between 302 and UN1.
This is my other Southern GT with a 351W. But same SGT adaptorplate. AP racing Clutch/ SGT flywheel & startermotor. Gear linkage also SGT.
I have an adaptor plate on my actual UN1 so I assume it should work.
Doe you agree with my proposal ?
If so I may com over on Tue afternoon to pick up the gearbox if ok for you ?
Now sold. It was great to meet you Fred. Best of luck with the gearbox. Hopefully I’ll have my ZF hooked up to my Twin turbo V12 for the 917K soon. Should get my uprights in a week or so. Exciting times ahead.
