SPECIAL ORDER REAR END

Racer Z · Post by **Racer Z** » Sat Jan 15, 2011 1:14 pm

I am looking at an eBay add for a 69 F100 w/overdrive. He says it has, "SPECIAL ORDER REAREND" with a 390 and 3-speed. I have sent the seller a question asking about the "SPECIAL ORDER REAREND". Are any of you familiar with this? I am under the impression that only huge trucks like F600 and up have a two-speed read end and that it probably isn't feasible to install one in my F250.

I am assuming that the overdrive is the "special rear end", but it's possible that they are two separate items.

Link to the eBay add:

Thanks for any input on this guys.

3spd with over drive means its a T89 overdrive transmission. he is probably refferring to the whoel truck was a special order truck and got a different rearend than was suppose to be used in that truck. i saw nothing that said 2 speed rear end in it.

fordman, you are probably correct. There is a much greater chance the overdrive is a part of the tranny and not a part of the rear end. I guess it was just wishful thinking on my part. I'll post the sellers response if I get one.

my wife had a special order rearend and it was good for the first 22 years of our marriage after that it started to hang a bit.

At least it didn't start leaking

If by chance it is on the rear end, it will be Hone-O-Drive. That is a very rare overdrive that could be bought, and bolts directly to a 9" rear end. A 8" rear end model was available also, and a divorced unit to. The models for those were 100 for an 8", 200 for a 9" rear, and 300 for the unit that is divorced that bolts in the tunnel of what ever car they are going on. A popular choice for RVer's as well as Hot Roders. Kind of pricey they are.

Based on your description, the Hone-O-Drive won't fit a Dana 60. Not giving up my floating axle. Sounds good for a 1/2 ton truck though.

When you hit a certain age in life, that stops being a joke.

It sure sounds like his description calls for a special rear axle. Of course he doesn't show any pictures of it or go to further explain what overdrive it has.

Looks like the seller responded and says its a Dana 60, LS, 3.54 gears.

limited slip that would explain why he says that. did someone say the d60 only came in 3.73 and 4.11 unless it was limited slip?

The seller sent me an answer to my question about the rear-end.

"IT HAS A DANA 60 LIMITED SLIP 3.54 GEAR RATIO REAREND"

Not the two-speed I was hoping for, but definitely a plus for who ever buys the truck.
