3 Speed OD conversion

[Mustang GT200]

I just acquired a cast iron toploader out of an old Granada to put behind my "hopped up six". It is a 3 speed overdrive unit. It is complete with the shifter, but the shifter is disassembled and I am looking for any info on how to put the linkage back together. It looks like it's all complete, 3 tabs to mount on the shift forks and 3 rods to attach the the shifter, just don't know what goes where.

It is different than a normal 4 speed as 3rd gear and OD gear are flipped as opposed the 3rd gear and 4th gear in a 4 speed. Also reverse is lift then to the left and forward as opposed to back in a normal 4 speed...

The OD trans should help with some of the road trips I plan to take.

Thanks

Hey Tim,
I wish I had some input for you on this,I actually have 2 of these transmissions (one from a granada,and one from a truck).They've been sitting on the shelf for a while I've been thinking about installing one of these into one of my cars(probably my 66 6 cyl vert). Unfortunately the truck one has a shifter on it,but the tailshaft housing on it is weird and the shifter is too far foward to work in a stang.The granada trans has no shifter. My thought was if/when I decided to install one in a car I'd take the better looking of the two and use it. I figured I'd mix and match tailshaft housings ,etc to come up with something.If you are able to post a couple of photos of what you have I'd be interested in taking a look? Maybe I can help shed some light?

I actually figured it out... Wikipedia and google image searches are a wonderful thing. From what I have been reading is the Granada transmission (which I have) came with a Hurst knock off shifter. It looks very similiar to a Hurst shifter. The stock location is a bit forward for a 'stang, but nothing a piece of steel plate and a welder can't fix (to modify the shifter location and lengthen the shift rods, not hack a perfectly good Mustang). Anyhow, I'll take some pictures before the install and share... I'm still in the process of cleaning and painting my engine compartment. It's likely the OD trans will wait as my regular 3 speed is all ready to go in... All this nice weather is killing me but going back to school has taken much of my time. My summer class end July 12th so hopefully I'll get the drivetrain back in a few days later.

Hey Tim,
I'm glad you got it figured out.You have to love the internet. I'd appreciate any info/photos you have as I am thinking of using one of mine as well. Unfortunately I don't have a shifter but I was thinking of possibly using a stock 65-66 Mustang Tailshaft housing and shifter? I'm in no rush to do the swap as my car has a perfect condition three speed in it currently but figured I might as well do the swap at some point as I have the trans sitting on the shelf.
