Thunderbird IRS in an AD Truck

[Coach529]

I am still in the planning stages for this project, but I figured I might as well document all the info I am digging up!!

I know this has been done before, but I could find very little documented in regards to a Chevy install.



ol' chebby over at Classic Parts Forum has one in his 3600 and I have spoke with him numerous time about it. Below is his truck....and another truck he built.



Good donors are 1989- 1997 Thunderbird/ Cougars and 1993 - 1998 Lincoln Mark 8. The Fords were on coil springs, the Lincolns are all on bags. Fords are available in 7.5" and 8.8" with drums and discs available. The Lincolns were 8.8 only, and only disc brakes. Depending on your location, they can be bought pretty cheap. I found a 8.8" in 3.23 ratio with discs locally for $250.00.

My plan is to put it on air. With this set up, you can lay frame without a huge notch, or relocating the height of the bed floor.

Below is a picture of the IRS in a TF truck.
