Wanted a happijac motor. Broken or not doesn't matter as only need the first gear.

Not having much joy with this request, people have been lucky to repair these or get them re-conditioned failing that
you might try these in UK I know they've imported items before

you can buy spares from Happijac in USA but of course you have to pay shipping and duty. having said that its a small part so shouldnt cost too much to ship. good luck
