I was talking to a guy at either DTS or National Drivetrain and he stated that Dana 44's were available on 84-86 3rd-gens and 92-94 Firehawks. He didn't know what models the early ones were or what RPO code or axle codes they had. But he did list the available ratio's as 3.31, 3.54, 3.92, & 4.09. I asked him how he got the info and he said from the data base on their computer. He then said that he also has an exploded view of the rearend like what the GM dealer has. I know that GMPP and SLP used to sell them but what about OEM????? Thanks. Dwain

I thought so too, but I soon found out from some TTA owners that they came with 3.27 Posi/Disc 9 Bolts.

TTA's came with 9-bolt 3.27's, and the only thing with Dana 44 rear ends I know about were the Firehawks.

My 84 Z28 has had two Dana 44s in its life. I'd have to check whether it was born with one or if they were both GMPP add-ons.

Apeiron, Please check. See if you can find an RPO code in your service parts I.D. sticker. Or you can look on the axle tube or possibly a tag on the Diff. for the axle code. Thanks. Dwain Brammer

From my understanding (and research), the Dana 44s were only service replacement items. No 3rd gen F-body rolled off the assembly line with one, they were returned to the dealer (or SLP) for replacement to a Dana 44.

The Dana44's were never installed on any stock 3rd gen from GM. This includes any and all 1LEs and TTAs. The only cars to ever get these rearends installed before they were delivered to the customer were the 3rd gen Firehawks from SLP ... that's it. However, you could easily go directly to your GM dealer and buy one ... or directly to SLP and buy one. Thus, there are several units in the general public that are currently installed on F-bodies but NEVER delivered installed with that car when it left the factory.

I know all of this because I've been looking for one of these rearends for years. I've run across several in my time. I am currently working on a deal to buy one as I write this. Hopefully I'll have one in about 3 weeks.

They were originally installed in the 89 TTA 20th anniversary Indy pace cars. I found this info in the Camaro performance handbook written by David Shelby.

Not sure if thats OEM though, it doesnt say who installed them.

That book is wrong then, because the 89 TTA's came with the same 9-bolt 3.27 ratio rear end that the regular 89 L98's came with.

Maybe the book is referring to the actual pace car, not the production pace car package.

no its a secret

My 1990 Pontiac service manual list serveral merchandising options.
RPO G80 Axel rear locking type (limited slip)
RPO G92 Axel performance ratio

I have not been able to find anyone who knows what these are. Also

RPO MM5 TRANS. MERCHANDISING OPTION 5-SPEED
RPO MX0 TRANS. AUTOMATIC

WHAT ARE THESE? MAYBE G92 IS THE DANA

Kevin91Z

iTrader: (1)

No... the standard rear end for f-bodies is 2.7x in automatics, and 3.08 in manuals. G92 means you get the better rear end, 3.2x in automatics, and 3.4x in manuals. Some cars also got 3.73's, I think they were the L69 carb'd cars.

Apeiron....I think you are right about that. It must be the actual track pace cars he was talking about. Not the street version.

Is anyone listening to what we (TRAXION, Kevin91Z, and myself) are posting? THE DANA WAS A SERVICE REPLACEMENT PART ONLY, IT WAS NEVER INSTALLED AT THE FACTORY!

MikeH, I don't care if you ignore me or not, so long as you don't ignore the facts. It's just when someone that doesn't know a certain fact is "told" by some that the feature was OEM, when in fact it wasn't, misleads the person who originally asked the question. That was my point. I wasn't agrueing the point of the '89 Pace Cars, because I don't know, but I DO know someone that does. Maybe I'll ask him when he is available about the pace cars and the Dana 44.

MikeH

mrz28ho...That fact was established many posts ago! The topic has turned to the Indy pace cars. when someone starts to think they know eveything they stop learning.

True. As soon as I can get a hold of my friend, Mr Pontiac enthusiast (should be back after SEMA), I'll ask him what he may know about the rear ends in the actual pace cars and let you know.

Now the next question on the dana 44. I found one here in the classifieds and when installing it in my car the driveshaft was to long. If you take the 10 bolt and the dana side by side the dana is .560 longer from the axle centerline to the centerline of the u-joint yoke. Was it part of the install to cut down the driveshaft?

Also a install note the standard 3-R u-joint will not fit the dana yoke so you need to use a cross over type u-joint thats 3-R to 1310.

When I converted my car back to automatic I put in a driveshaft from an 85 IROC, didn't need any modifications at all.
