Mines out of a 95 t-100 truck wich took a 3.0 adapter to go with a geared t-case your t-case may be a geared you need to look and see if it is divorved or combined. If you call marlins and he's there he can probably answer that for you i've seen them botth ways :thumbs:

There are ways to make that adapter work without loosing fluid on severe angles. My frien mike runs that setup with AA5to1 in the rear case and stock ratio in the front, on 40s. Once you work out all the bugs that inchworm didnt account for its an awesome setup.

Alot of people diss the early autos but with gear drive cases all the downfalls are removed, along with the chain case, and extra clutches in the tcase.

My friend and I built a thin plate that bolts between the transmission, and the origonal reduction housing of the old tcase which is retained when using the inchworm adapter. He would have to sit on an extreme angle for a long amount of time in order to starve the transmission of fluid. He does still over fill the transmission, but only by a quart or so. Its my thought that that extra quart is constantly filling the otherwise empty space caused by removing the guts from the reduction part of the origonal t case. 

I belive skyway makes an adapter that also works with the early autos. I used to have a crawl mag that listed tcase adapters. It had a link to a website for skyway, but now I cant find it or a link. I do know there is another adapter avaliable though.

Skyway Transmission makes the gearslug.  Don't know anything about it though.

YOU ONLY NEED TWO TOOLS IN LIFE - WD-40 AND DUCT TAPE. IF IT DOESN'T MOVE
AND SHOULD, USE THE WD-40. IF IT SHOULDN'T MOVE AND DOES, USE THE DUCT TAPE.

IF YOU CAN'T FIX IT WITH A HAMMER, YOU HAVE AN ELECTRICAL PROBLEM.

Marlin wouldn't copy it because he has ethics and morals.... i wouldn't be too sure about a certain competitive company though....
