Dittos and mega dittos.

Pretty sure the 'late' Olds/Pontiac's are 9 3/8ths. Not too many ratio's to choose from.

Sure wish you were going to be at Spokane, Aubrey. I'd really like to see your '62 in person. Any chance of that?

I'll have the current rear end re-geared this week, Ken, and the car will be ready to go. No money for another big trip though. Next outing will be Edmonton, for the IHRA Rocky Mountain Nationals. Same exact weight... but dropping into D Stock ( because of a somewhat soft HP factor ).

As for the final solution for the rear end, yes, I would be more inclined to use an old Pontiac/Olds rear... but as has been pointed out, I don't think it fits within the way the rules are written.
So, for this season, I'll make sure I have a couple sets of 5.13's on hand.
However, I have come up with a bit of an "off the wall" idea ( I know, the car is already off the wall ) as a possible solution, which I will attempt to to put into motion this winter.
In the mean time, it's so off the wall, that I dare not mention it !

You are allowed any GM corporate rear upgrade which includes the late 1950's/early 1960;s olds/pontiac rears that are beig talked about on this thread. Good luck. Thats a cool ride.
