I had to do some reconstruction of the blower case but the Mopar Performance valve covers fit with plenty of room. I tried the blower motor that was smaller and it wouldn't work. If I put the valve cover on first, there wasnt enough room to slide the blower motor in with the cage on it. if I put the blower motor in first there wasn't enough room to put the valve cover on over the rockers. And it wouldn't work either with moving both around at the same time. So I had to make a decision. I wanted these covers on so I took the blower motor out and the case splits into. I reversed the ends to where the end went up inside the base and welded it. then I fiberglassed the seam and here is what I came out with. I have never had the heater or defroster on in this car because I dont drive it in cold weather or rain so it lost the battle. With that being said, I have a nice set of M/T valve covers for sale in the proper section. Thanks guys for all your help and ideas. let me know if these look better. I have a couple more changes to make next week in the engine bay.
