I just put an XS starter in my '68 390 GT after the FPA headers cooked the original (factory) one. Go mini for sure (my $0.02)
Good to know as you have the same car and headers. I'm thinking I'll end up buying an XS starter.
They fit our set up, are a known brand supported by big stores, and apparently they work well.
Plus I can keep my stock wiring...
I would have liked to consider a Proline Perf AZ starter but they never sent the specs or photos as they said they would. Its a bit hard for me to make a choice in their favour with no info or images to go on! Their website being down, lack of Comms, and no info provided doesn't exactly inspire confidence either.
UPDATE: Well I just ordered a Powermaster XS Mini starter from JEGS. I feel most comfortable with that option. Seems it always fits, they reply when questioned, their website actually works, etc...
Thanks for everybody's input, appreciated.
