There's a guy by the name of Brad Durst in Tx that is offering new parts and service on these Pont/Olds 9 1/4" rears. Last year they made a run of 3.64 ring and pinions through Mark Williams and they fit the more common 2.78-3.23 carrier. He had a parts and service list too. If you want his phone number, email me. I haven't dealt with him except for buying 1 set of the 3.64's but, he may be worth a try for parts and service work. They are also seen listed on ebay often.
When building my front motor top fuel dragster, I wanted to make it ALL Pontiac but, since there is no quantity of pro series 3.90 gears, I had to use 9" parts. Only 3.90 gears are allowed for the class.
This is a pretty good web site but, it is put together wrong. Why do they have a '61 and older column and then a '62-'66 one? It shoudl be '60 and older and such. I can only guess that whoever put this site together is not familiar with big car stuff. Most everything of interest to '61 people is of intertest to '62 people. '61s have almost nothing in common with 60's. Where '61 and '62s are almost the same mechanically. Oh well. Still it would be easier to reach everyone of interest by not having to post the same topic under multiple headings. This subject of 9 1/4" rears may be of interest under the racers list too. Steve
