Hi Danny, sorry about the delay in replying. I have rebuilt my cross members by copying the remains of the originals, but I dont have any mudguards to refer to so will make them to fit. There does appear to be differences in body construction from the little I have seen. Rippo is really the man to ask, maybe he'll be along here soon!
In the mean time I have continued with the body sides. I could not find any suitable hinges anywhere so have fabricated some, hope they dont look too bad and will pass muster! One dropside now has the metal edging all the way round.
