I just got done installing my electric replacement motor from car and truck orange co. , much larger than oe vacuum motor , sat in nice but,motor is very close to speaker grill ,motor wont fit up against the firewall has to be reversed so doubt i would ever be able to get a speaker in there , had to pull wiper arms of inside cab , brass bushings were to small to fit on the bar so had to remove them and use the plastic ones provided , seemed to work good , adjusted the wipers on the windshield to good park position, not bad for an offshore brand . we'll see how long it lasts .
