I am putting Vintage Air in my 68 327/350hp car. I am having trouble getting the pulleys right with the AC add on. So far I have added the third pulley to the crank and every thing lines up except the PS pulley. From what I am told the PS is shifted out to the third groove and runs directly to the crank. I purchased what was supposed to be the right pulley to bring the PS farther forward to line up with the third groove but it only brought it half the distance. Can anyone tell me the right pulley to bring it all the way out or if this is the another way I should be setting it up? Thanks for the help.
This is how mine is setup. It was a 327 350. I installed Hot Rod Air in 2005.
I bought the water pump pulleys in 1992 from a company called ASL Company out of Sparks NV.
Mine are deep groove pulleys. The numbers below are from my receipt since I don't really feel like removing them....
The 2 groove water pump pulley is 3995641.
The add-on single groove smog pulley is called a "235" on my receipt, but I suspect it is the 3883235 shown on website below.
My PS pulley is Power steering pulley (deep)(GM) 3834720. I got this at a GM dealer 1991. Cast Iron.
In 2005 when I installed a/c, I bought Crank Add on pulley from Zip.
M-3388, 63-68 P.S. Add-On Crank Pulley (Deep Groove)
Equivalent to GM Part Number 3916385.
In 2005 I installed a generic ps pulley "backwards", and shimmed, so I could run all the belts.
Just this year (2014) I put the normal cast iron pulley back on PS pump. I'd been running a generic ps pulley installed backwards for about 9 years and ran it off the forward-most pulley. It wobbled a bit the whole time.
This year I cut and adjusted the A/C compressor bracket and moved the A/C belt to the forward-most pulley on the harmonic balance/water pump. The PS cast iron pulley belt now runs on the 2nd pulley and the Alternator on the inner pulley.

Thanks for the info. I will research them for parts information. It seems like I have spent hours trying to come up with the right solution. Apparently this is another 68 unique problem from what I am being told.
