you need a Corvette Shop Manual, year specific... but the Alum Dana 44 is a finickey bitch.. you might want to pull it out and get some experienced help setting it up ...the 3.73 gear is a perfect match to the 700r4 .. I started with the 2.87 , swapped for a 3.31, still not enough..finally swapped to 3.73 and its perfect

The Dana 44's are very difficult to overhaul without having a bearing separator and dummy differential side bearings. Definitely not a rear end to learn on. As it is a Dana Spicer rear end any of the Dana Spicer dealers can overhaul it for you. And as Fish said, the 3.73 ratio is the best ratio for use behind any overdrive transmission.

For the DANA 44, you need Mike Dyer. He's in the Dallas area and has developed a bunch of goodies to make the '44 stronger- steel caps for one. He does a lot of rear ends for Corvettes.
ANd he's got all the tools for the setup.
Google " Mike Dyer Corvette rear end"- he comes up there.

Hmmmm, this like a real peach of job. I orderd all the parts earlier this week from Advance Auto.

Thanks to all for the info. More to come. :)

you already ordered the gears ? you need to go ahead and refresh the whole thing while its out...don t want to do it twice.. nothing more annoying than having to take it out again
Yep, did that when I ordered the gears. Ordered the gaskets & bearings. Comes as kit. Figured while I"m there. I said that a lot when we had the engine out. :rofl:
