i didnt have that big of a problem with my prothane instal...i didnt use any fancy dogbone mount however i just pressed the prothane insert into the factory plastic one and didnt look back...the only problems i ever had with the prothanes were the belt side engine mount , the first one the feet cracked off on them, the secound mount was just a bitch to line up and finally it went on...aside from all its actually not that hard
