Does the stock Differential from the manual transmission ZL1 with 3.73 Ratio fit in my L99?
I am thinking about to swap the hole diff. Thats cheaper than a gear swap in germany. Here in Germany wants the garages about $ 2800 for an complete gear swap include all stuff needed like ring & pinion set, Seals, bushings, adjust and so on.

i want to hear another answer, but
Then the GM 3.73 ring & pinion set also does not fit and i have to take aftermarket brands?

I have a whipple super charger and making around 600rwhp with a 2800 stall now. I really want the 3.91's but I'm afraid I would smoke right thru 1st gear. Is there a big difference between the 3.73 and 3.91 and what would you recommend for my daily driver/occasional track car?

I would definitely dial it back with that much power. The auto trans is already geared more aggressively than the manual.

It was an entire rear end swap (I have my old 7.6" IRS in a box in storage). If it had just been gears this upgrade would have been much easier.

Great info! Will have to spend more time in this part of the forums to learn as much as I can before swapping in the rear diff I just bought with 3.91s
