AlanG Posted May 15, 2022 Report Share Posted May 15, 2022 To add a type J o/d my 4A gearbox I had to use a hybrid mainshaft because the J type has a metric spigot. I think adding a J type to a later TR250 just a standard new J type mainshaft will be required. And the adaptor between the g/b and o/d. Alan. Quote Link to post Share on other sites
TR4Tony VC Posted May 15, 2022 Report Share Posted May 15, 2022 Hi Peter It’s worth talking to Pete Eggington at ORS as he supplied all the bits to do the same job for me about 6 months ago. There are some obvious things but you can do a lot ‘while you’re at it’ to make for a much better operating box and OD unit for the same money. regards Tony Quote Link to post Share on other sites
