Barracuda Header Problems - Starter

When I decided on a high performance 318 for my Barracuda, I didn't want it choked off with the stock exhaust manifolds so I bought a (very expensive) set of TTI headers. I knew there would be issues - the Barracuda engine compartment doesn't exactly have a lot of room. I didn't know what a P.I.T.A. those issues would be though. The most annoying one is the starter. In the instructions, TTI calls for a specific starter that is no longer made. Other mini starters, even so-called "clockable" starters, won't fit. I got ahold of TTI and they refered me to another vendor who makes starters that supposedly work with the TTI headers. Called them yesterday and found out they do make the starter, but they're missing some parts for it and won't be able to ship until Feb 15. OK so if I can find a starter that works, so what, right? Well, no. What if the starter goes bad and there is no longer anyone making a replacement that will work? I'm screwed I guess. I wish now that I would have gone with Doug's Headers. They're harder to find than the TTI's but from what I've read don't have TTI's issue with the starter (or with the pitman arm, bellhousing size, ...) Oh well, live and learn I guess. I don't want to have to go back to a stock exhaust...
