TTI Headers I picked up cheap....

Plug access is sufficient. I would definitely put some kinda of insulating boot over it though...other wise I'm certain the wires would be toast.

Starter Access: I dunno. Take a look. I don't have a starter/or mini starter, so hard to gauge. I would think I'd be able to get in there by loosening the headers.

I just installed Tti headers on my 74 dart sport. Starter must be installed first. I used a starter from a 99 dodge dakota 3.9l motor. Hopefully I'll never have to change the starter
