sounds like you will have to cut them off like i had to,one of the bolts goes up into the boot floor which is stuck down and looks like a washer,the big bracket you can buy from fords with the new mount rubbers in it already the other 2 parts of the bracket i powder coated as they were alright,the 3 little rubbers are still avaliable to,and so are the bolts which go to the body,they list a couple of lenghts but i just ordered the lot,all the other nuts,bolts i got in stainless,hope this helps,sorry no part numbers i cant find the receipt.
