Broke some teeth on the pinion gear in the roadster unfortunately and just got around to dropping the center section to assess the damage, but not sure where to take it to get setup. The car has a 58 pontiac/olds rear and I'm also looking for a gear set (4.88 or 5.13s) if anyone happens to have something available. I talked to Hooper's a little while back, but they didn't instill any confidence in me that they were comfortable working on the rear since they couldn't quote me on parts or labor .
The GEAR SHOP (FORMALLY TOMS DIFF) in Paramount 1-562-634-1396 Tip: buy gears yourself and just have Gary do the setup right around $275 plus any bearings & seals

Ramjet on San Fernando Rd in Sun Valley. Ask for Eddie. He's done several for me over the years. I may also know of some gears. PM me
Did you ever sort this out? I know a place that does great work (I've seen your car locally), and have a friend that has some of those "low" ratio gears
