Okay, I bought the vintage air system for my 74' 40.....really nice unit, but, since my truck is the transition year, I'm having a few fitment issues. I've included some pics to show my concerns.
1st off: I had to use the outer pulleys on my water pump and crank, since the compressor sits a bit forward in the supplied bracket and has no tension adjustment. No biggie, as I made some adjustable slide brackets to mount on the compressor/bracket.
2nd: The pulleys that are there are kind of skinny. I'm using a 1/2" v belt that fits (on the smaller side) of the compressor and seems a tiny bit wide for the truck pulleys. I ran the engine for a while and it didn't seem to want to jump the pulleys, but thought I'd see what you guys think about the 'bite' of the belt on the two truck pulleys. I don't know if there is a narrower belt, but it would probably be too narrow for the compressor pulley. This one is in between the best size for the compressor and the best size for the engine pulleys.
First pic shows what seems to be a slight misalignment of the path of the belt....is this enough to cause serious problems? or just accelerated belt wear? or am I being too anal?
The second pic shows me folding the belt over inside out and pressing the 'v' into the groove to show the purchase that it gets on the pulley.
The last shows the adjustable mount I added to the bracket.
And lastly....the engine bay is usually much cleaner that this....I'm waiting till the install is done....
