Pinion angle question

If you check any rear end, you'll find they are between 3* - 5* up in relation to the pinion center line. There's nothing "arbitrary" about it. That's just where they all are. I prefer 5* simply because that's a little more conducive to a performance rear suspension, but anywhere between 3-5 is acceptable.

You're right - Stock A body housings put the pinion at a 5 degree upward angle relative to the perches. But if everything is loose, why not just wait til everything is in and get actual measurements to put the pinion angle exactly where you want it? It's the same amount of work at that point.

I guess he could always set it to stock and adjust with shims if absolutely necessary. But at that point, it's probably splitting hairs anyway for a cruiser.
