Depends on the type of mounting and aft most bulkhead on the tailcone. Forged ones are found on later 152's only, everything else has the sheetmetal bulkhead and its kit.
All swept tail 150's and early 152's use SK152-24A
Hung is right. I just looked at my notes of things to buy and I had written 24A, I just didn't bother to look at my own notes. Oh well, anyone need a SK152-25A? I'll pay shipping.
I have a 1980 F152 Sn 1802, but haven't had the chance to check on the bulkhead issue. As long as the bulkhead is ok, I would want it. I assume the kit would come with papers?
