I just got a used fox truck mount with a nissan engine and the blower locked up. i took it to someone and they said it would be about $5500! because he said there is only to supports on the engine instead of 4 and the machine most likley shakes and that might be the reason my blower messed up. Does this sound right? where can I find prices on a blower? I do not know much about this kind of unit..any help would be great..thanks
