Hello, look at the picture, maybe someone knows from what car to get this joint to fit bike propshaft adaptor. Or maybe these joints are manufactured? Original sierra joint looks too big and the holes didnt fit.

I'm not far off fitting the engine into my Mk, but I'll either get them, or MNR, to supply the complete prop and adapter.

I'm thinking it'll be easier in the long run.

robin reliant sliding joint is what is used but some kit car companys
