Rear suspension bushings for '91 GT

[Codosuarus]

My '91 mustang GT convertible has been sitting for about 10 years and now my son has taken an interest in it.
He pulled out the rear control arms after finding that the suspension bushings have all either melted or disintegrated.
We are looking for new suspension bushings (urethane is fine) but cant seem to find them.
I remember that I bought aftermarket rear control arms around 20 years ago, but I cant remember where I got them and they have no markings.
Any ideas where to find these suspension bushings?
If not, Is there someplace where I can buy them by dimensions?

Would really need to know what the arms are as not all bushings will fit all arms. Do you have photos?

Those look like old BBK control arms, which you would use these bushings

I had this issue on a customer car. He brought us control arms that were off the car and missing bushings. I had to measure the dimensions inside and I called prothane to get a set. Ended up needing to cut them down as they were too wide, but that wasn’t a big deal.

If I had to do it all over again, I’d just tell him to order new control arms. Since he had them powder coated to match everything else that wasn’t an option though.

I think that your BBK theory is a good one. They sure look like the 99 to 04 control arms that you show.
Also, almost all the other parts that I put on my mustang came from BBK as I have generally been impressed with their stuff.
I will call them.
