Warn overdrive with dana 18

So I bought an overdrive with matching planetary gear for my dana 18. Got everything installed except the overdrive. My ******* starts to put it on and bam ****er won't work. Didn't realize that a front shift overdrive doesn't bolt up. So what the **** does this overdrive work with? Maybe an early dana 18

it is a Warn? What is a front shift overdrive? AA holds the patten for it now, sold under the Saturn name. What don't fit? There is a company called Hrem? the overdrive guy ( I think) that sells and knows a lot about the Warn overdrive. I know there is a 33 and a 29 tooth gear and they have to match and there is a small hole and a large hole case. I had a couple of them back in the early 70s but both of mine were 47 18s in Jeep CJ2As.

Front shift means the shift engagement lever is to the front of the unit

I didn't know Warn even made a front shift option on the 33-29. I thought the front shift was only with the very early models like a 20-29. A front shift, as noted, will not work with the 4" index late D18 or D20 housings.

Best place for OD info is Herm's site

http://hermtheoverdriveguy.com/

Herm Tillford is extremely knowledgeable and will take the time to talk to you and is ameanable to trading parts.

Besides, he has a nice looking 3B on the header

I see no information on exactly what you are working on but if your Jeep has the V6 (only ones that used the large index T case) and the optional 4.88 gears, it is the absolute best improvement you can make.

If ur in Alberta it would cost a fortune to ship axles but the overdrive would be reasonable. The axles are a dana 44 rear and 27 front. Chromoly axle shafts 4.88 gears with lockers.
