My setup is going to be somewhat different, I have the AWD transmission with custom front & rear mounts. I believe I set it up to bump it a bit to the d/s for better balance up front.
There's a PnP for the Capri as well... you're going to do MS though, I'd do it right. Get Miata CAS and coildpacks or do a ford EDIS-4 ignition. The PNP's are great but you're still left with crap ignition systems, which is one of the major reasons of going to MS in the first place
That said Escort harnesses are easy to come buy on Clubprotege, I think I even have one myself
