PowerHaus-II shows a HB ( HB 19:31 1.63 ) gear. Charlie Davis' gear chart has an open spot where HA would be for a 901 box, so i donno if they "really" exist.

but try PowerHaus-II and see what they say. then report back...

this one should be pretty easy :-)

we know it's not a 914 ratio, therefore the answer is "some kinda 911 or 912 prior to 1972." you'll need to spend some time with ETKA, i think, to run it down - this is your project, not mine.

just pray it's not a 911R ratio...

HB was the 2nd gear in the 901/06,10 and 12 as well as the 905/00,01 and 13.
HA was the 2nd gear in the 901/53,54,78,79,83 and 84

Yup, that's bad news. Might not be available in a standard form. The H gear is easy, it's second in a 4 speed, and on the 4 speeds it's first that's fixed to the sahft.

905 is a SportoMatic (and therefore 4-speed) - yes ?

I suggest you get the body work and paint done before you go changing any other mechanical stuff in your car. You are always complaing how it looks, stop worrying about the go faster parts and make it look good. Actually, it doesnt matter how it looks or runs, I am still going to spank you at the next AX.

Aaron,

I have a slightly used HA. Bought it years and years ago for
my 901 with a 904 mainshaft.

I was going to give it to an old friend of mine- Topper C.
for his collection.....but what's it worth?

You have 15 inch wheels? Why not go to 16s, and go up to stock rolling diameter?

See, I detest nerf tires, and you should too, although I know you like that frame rail on cement feel.
