Lightweight chassis on a series?

Chaps now you have convinced me not to make a hybrid 90/series chassis, can anyone tell me the differences between a light weight chassis and a series SWB. Would I be able to put all my series panels/bulkhead etc onto a LW chassis without having to weld new outriggers etc? I might be able to locate a Galvo LW at a sensible price.

air portable chassis is narrower than a series so nowt will fit straight on

Thanks Yella.

I had a series 2 swb truck cab and the rear crossmember didn't quite look right until someone pointed out that it was a lightweight chassis! All the panels etc seemed to be in the correct place and in order, it also had a 2.8 german ford V6. Very fast but all round drum brakes were a bit dodgy to say the least!
