TTI shortys

Well dangit my starter went out. The car is a 71 Duster 318 PS with a 400 on elephant ears and A/T, with a pair of old rusty Hedmans on it that someone beat on until they fit. It's a full size starter.

FWIW, no way is that starter coming out without picking the engine up and taking the headers off, so I'm in a pickle. If I'm going through that punishment, I'm going to replace the headers to avoid the hassle of getting the Hedmans back on and starter problems in the future.

Schumacher's aren't available for several months so they're out. Has anyone tried the TTI shortys? Are they as trouble free to install as the Schumachers are?

Thanks,
Bob
