403 The new Gear Vendors overdrive (yep, traded in the old one) uses the larger TH400 pinion shaft. That's good. But it no longer has the extra mounting boss I was using to hold the drive shaft safety loop. Here's the solution to not adding holes in the car. Just flip it 180 and bolt it to the seat belt mount. It's a lot stronger than using small bolts and washers.
Well, time to go racing, sorta. Next race isn't for two weeks, the first weekend of June.
