I have a z-bench (pretty sure that's what its called) from a 1990 Donor
Syncro, to replace my other bench, which just folds forward, instead of the
collapsing/flattening action of the Westy style bench.

I don't remember having any issues taking it out of the other van, but its
been nearly a year since I did that, and I can't get some of the bolts in.
 There is a plate in front of the lower bolt (behind the wooden foot panel.)
I don't remember having any issues getting it out, but this time the bolt is
concealed... Has anyone else removed and reinstalled this type of full width
bench?

Help is appreciated.

1987 VW Vanagon Syncro.
