Very good info,I just printed this off for my old files, because I only got a parts book and nothing else, I bet you have a complete book on how to fix thinks.

Looks like the C-trunk has a reduction in it. How would you get a large plug (rock, hard concrete, debri) out of it if happened to get stuck in there?

Biged, Its from a sales brochure early 90's. However, if you need documentation let me know i'll gladly scan and assist (mostly for "C" trunk)

if you have any doc's on c trunk i would love to have them, just bought a 24 4 sec , user book came with it but i dont speak french :) will post pics when it comes back from paint shop

The trunk was and is one of the best set ups for a mobile , Very reliable and very easy to work on or repair... Im a big fan of them!

thats good to know drew if you have info it would all so be welcomed
