Got my 88 back with the new gears. It's a major improvement over the 2.73s.
It really accelerates much faster. I didn't expect such an improvement with a 3.07.
The 3.07 ratio seems to be almost a perfect match for an L98 with automatic . I have 3.45's in my 93 LT1 and they work well. I tried 3.73's first and they were too steep for my taste.
Did you do the bearings and seals or decide to toss the dice and try it as is?

I had it rebuilt with new clutches and bearings. I don't have a lift so I had a differential shop do the work.
Before posting this I got the ok from Fred. I have a Dana 36 pumpkin with 3:07's sitting in my garage. Out of my '90/auto. Has 97,000 Arizona miles on them. Nothing wrong just replaced them with a Pete Kane 3:73 pumpkin. They are in Cave Creek, AZ & I would sell for $275.00 plus shipping. When Pete shipped the 3:73's from PA to AZ the DHL price was approximately $75.00 last year. If there is any interest send me an e-mail so I can respond with pictures. Thanks for letting me post this Fred.
