A518 Questions

A 518 is not gonna fit without floor work, either. My understanding is that only the smaller A500 (904 based) will fit and even that requires what might be called extensive rework of the crossmember. There's a thread on here about that

I think the 518/727 shifter is same

I'm planning (if i live long enough) on an A500. It's a 46E series, meaning electronic. I've read (Transgo? I think) that you can turn it into an "all manual" box, needing a toggle or whatever and or vacuum switch for the OD.

A500 42RH swap
