Al on vwcaddyforum is doing the same in a Mk2 escort. He is close enough to you that he could do as much of yours as you want doing. He has recently started a new business called retro fiction do do these sorts of jobs and has a well equipped workshop and has brilliant fabrication skills and seems to know his onions on most car subjects and is well connected for ecu work etc.

The qpeng stuff is quality too, the mk2 swap is very simple on the mount side of things, mk1 is much harder but sorted now the market is full with people doing them. Al did mine the hard way and grafted in the mk4 golf mounts in to the mk1 chassis legs.
