I bought mine from Impco last year for $175. Of course, that was before the PatsShop was online. I suggest you check there as well. As for the procedure, mine was rusted on REALLY tight, as Benzmac said. Had to cut it off with the Dremel and a cutting wheel. During the process, I wished I had gone to a pro. Afterward, however, I'm proud of having done the job myself. It's just a matter of how much time you want to spend and how many bad words you're prepared to say. If you do this, buy new bolts as well because you won't be able to reuse the old ones.
