87 Winnebago Chieftain AC and fan parts

[byekryam]

Ok, putting other issues aside for the moment.... Leaving Friday morning and having two issues..... I have an 87 Winnebago Chieftain and went to the auto parts store for a reciever\dryer and a fan clutch for the AC and fan and my mechanic states they're not the proper ones for the RV. It's what the auto parts store pulled up for the year and motor and AC. The mechanic doesn't have info on what the proper ones would be. I know that it's a Winnebago placed on a Chevy frame and 454 but not sure who the proper people are to contact? Winnebago? Chevy? Other builder of these RV's? Under the gun to get this purchased, shipped, delivered, installed so reaching out for whatever wisdom anyone could offer. I will feverishly research tomorrow morning, but it's not exactly my forte..... Thanks
