Al,

Your right on the = money,=20 everything you have said is true and slightly different for different = starters.=20 Tracy uses the manual starter as that is what Ross initially did and = it's=20 carried on from there.

For the Aussie = Bellhousing I=20 uses the Turbo starter but have made allowances for=20 both.

The Subaru starter = will also=20 mesh with the Mazda ring gear.

The mounting holes = are all=20 different.

The starter snout = hole doesn't=20 need to totally surround the starter, so you can start from the edge, = cut a bit=20 and check for fit and then take out some = more.

I liked the = optional bolt hole=20 mount, I didn't think of that. As long as it's held firm at the mount=20 holes.

I tried to send a = photo but it=20 didn't work, it bounced because of the = limits.

George ( down=20 under)
