Ifor Williams back

Hi , will a Ifor Williams back off a 90 truck cab fit a series 3 truckcab

No to long. But you can shrink these. Take the front out(pop rivits)
Move to required size re pop it then cut.
Cut mine down.

I took a long one and shortened it by a foot and narrowed it by 6 inches. Took about 200 pop rivets! (and a dozen 3/16 drils...) Shortening is easy, use the frame as a guide then cut the bit you don't want off. Narrowing is a pig as the sheets are glued at the top but 1" sq fits inside the channels so you can use that to join the frames. I made it fit a Sankey, now its done it looks good.

Cheers guys
