Welcome! Sure does sound like a neat project! If my memory was better I would direct you to a shop in Dallas that specialized in Jags, both restoration and performance parts and service! Unfortunately, about all I can remember right now is that was up on the North side someplace!!! Heck, it was at least a couple decades ago, not even sure if they're still around! I'll check around and see if I can find some information that is a bit more helpful! Anyway, good having you here, an E-type from the late 60's is still on my dream list!
