Looks like the one I sold a few years back-

 

What's that?The 2XT Double Trouble or the engine crane?

 

The crane-

 

It's a Hien Warren,and ive had it 15yr.'s.Been real good to me.

 

Here is the 1984 Popular Mechanic's january issue about this 2spd aux. tranny gear box.
Popular Mechanics - Google Books

 

This has to be done to fit the transmision gearbox into the back of the overdrive unit.

 

The cross member that use to saport the transmision,and transfer case is now just used for keeping the frame rail's tight,and straight.I started fabrication of the cross member,and I only have to add a couple of peic's of iron on botom to make it super stron.It had to have this drop becuase transmision is now back 7"-5/16 from it origanal location,and it make's the bottom of transmision fit in that droped area.

 

I am very interested in seeing how this turns out - thought about doing something like it.

 

The instruction's for the aux. transmision say to use a GM tranny mount,and im so diehard FORD I could NEVER put a GM part in my truck.So I made this block that has a GM mount bolt pattern,and on the other side of it has a Ford tranny mount pattern.The bolt's that hold Ford mount are welded in so I only need one wrench to take off in futur if I had to.

 

Here is the aux. transmision in truck.Notice how far back shifter is before I fabricate a new shifter handle.

 

I hope this help's.If someone was to buy and install a Ranger overdrive unit this will really help with the install.

 

Well after spending a bunch of time fabricating a crossmember as seen in above pic.'s,and installing it worked super,and I will have some pic.'s to share.I installed transfer case today,and like a dummy I totally forgot that the front driveshaft has to pass threw there,and now with it being 7"-5/16 moved back it hit's the cross member we made up.So im just going to take the member back out,and weld in a 5"X5" steel square into the member where the driveshaft will go threw.It will also act as a driveshaft saftey loop.I will post the pic.'s tomarow after I weld it up.Other then that the member we made the drop in fit's perfect with just the right amount of clearance for the bottom of tranny.Here is a couple of pic.'s with it installed with out the square for the front driveshaft to pass threw.

 

Well it's all in,and driveshaft's bolted up.I had to stop install to do some side vehicle work to help pay for this project,but I was able to test that truck while pulling it out of the shop.I was not able to use that crossmeber we made,and I had to make a whole new one just back 7"5/16 back from oem member.With the oem member bolted in oem place it wouldn't let the driveshaft for the front pass threw.All I have left to do is bend a new shifter,Hook up a 3way toggle switch for shift motor,redo my exhuast.I have some sweet 3" chrome stack's that will go with the rest of the mini big rig truck look,and drive abilety.

 

Good man. Thanks for update. Look forward to final successful report.

 

I've enjoyed reading about your overdrive install. Very curious as to the driveabilty of it. Have you finished it yet?
