Dave Ashworth Posted November 30, 2018 Report Share Posted November 30, 2018 Is it possible to replace the TR250 chassis with that from a TR4A? Or are there many differences between the two? Any information is very welcome. Cheers. Dave. Quote Link to post Share on other sites

ChrisR-4A Posted December 1, 2018 Report Share Posted December 1, 2018 Dave, would a 6 chassis not be a better easier swap and probably a lot newer? Quote Link to post Share on other sites

And if you aquire a later TR6 chassis this would also have the advantage that all reinforcings are already included. Waldi Quote Link to post Share on other sites
Dave McDonald Posted December 1, 2018 Report Share Posted December 1, 2018 Dave, I believe the TR4A chassis is different towards the back end. Where the TR5/250/6 chassis has a top breastplate at the narrow part of the chassis, the TR4A has a horseshoe type of pressed steel reinforcement instead. Just look on Moss website for the pictures to see difference. Don't know if that horseshoe is attached to anything else, e.g. the diff front bridge and whether or not it can be removed/replaced with the TR250 top breastplate.

ChrisR-4A Posted December 1, 2018 Report Share Posted December 1, 2018 Don’t think the horse shoe bit is affixed to anything else but at the rear end the Tr6 has an additional 2 fixings to the tub on the rear seat area. Don’t know if TR 5 has the holes in rear seat but could easily be drilled and helps to stiffen up chassis. Chris Quote Link to post Share on other sites
