I called checkered racing where I purchased my front clip and power rack to see what they could tell me and it wasn't much. They did confirm the rack was for an 85 t-bird but that's about all they knew. I was thinking of going to the local NAPA store and getting a hand full of fittings both standard and metric and trying all of them until I find out what type threads the rack is. Then, once I find out what type/size the threads are i will be able to find the correct rack fittings. If you do a search on ebay for "power steering fittings" there are several types that come up both standard and metric. If I do find out for sure the sizes I will definetly let you know.
