This has been about 15 years ago, so I may be dreaming some of it up but it seems like when we were trying to re-assemble a 71 Beetle I bought as a basket case, it was missing the shift rod. I think the one I put in it came out of a 75 chassis I bought for the tires . . . and I had to have a buddy of mine cut the end of it off, shorten the rod 40mm and weld it back on. Again, it was a long time ago so I could be wrong on what the rod came out of and what it went back into, but I know it had to be shortened and I'm pretty sure it was 40mm.
