It was going so well then D12 / D13 came along

[gingea1pom]

I can’t offer an answer to your problem, like most on here I would love to come over and be a second pair of eyes on a re-measure. Also I have built my rear end to take a Suturn rear tub.

If it is any consolation D13 only supports RP1 so not critical like a suspension mount.

I found as my build progressed and the basic chassis was in place, you can be less critical with book accuracy. After all the discussion on here over steering wheel support frame, I took some advice and clamped the steering column in about the right place and built the support around it without referring to the good book.

Not much help really but rest assured you will either work it out or decide it is not that important.

Sorry to waffle on but SWMBO is watching Dancing on Ice.
