the crank pulley is 2 piece, the 3751232 is only the add-on 3 rd groove for power steering


I have power steering and ac.
is there i diagram somewhere that shows the belt placement for 75 2+2 w/ac and ps.?

Yes, finding all the pulleys and brackets will take some searching and a lot of asking. Google pictures of Monza V8's so you can get an idea of what the brackets and pulleys you need look like. That's what I did anyway, searched for mine for a couple years to get them all. I will say this, almost everything I found was by asking someone, I didn't find them listed on eBay or Craigslist, I did ultimately buy most of them from people that were listing other Vega/Monza stuff on those sites. My cars are not AC cars but the cars I have seen with AC use a combination bracket for the AC pump and the alternator so have a good look at some pictures so you will know what you need if you want to keep the AC. When I found a listing that looked promising I would message or call the person and kindly ask if by chance they had any of the items I was looking for, you would be surprised how many times they had a piece I needed.

As for the fan and spacer, mine are not currently installed on my motor as it is only in the early mock up stages (checking fitment and belt alignment). I can dig around and find them and take pics of them if it will help you out.

I also forgot to mention, I was able to get some exploded part diagrams of the Power Steering Pump and brackets from my local GM dealer. Now none of that stuff is available for the dealer anymore but they were handy to see what the part looked like and a part number as some people that list items for sale also include a GM part number for the item.

I have all the brackets with ac and ps. They took the pulleys with the engine in 1985 when they pulled it.
Everything else was in the back of it just as they left it.

thanks for all the Information

Hi Keith,
I have pics of my fan and spacer if you need them and my motor is mocked up on an engine stand. I don't want to take it apart but I can take pics of the crank and water pump pulleys if they would be of any use to you. My car is not an AC car though. Let me know I can get at it pretty easy.

All I can add is my 75 V8 Monza which I purchased brand new did not have any spacer between the water pump and fan. Actually there is no way it would have even fit as the clearance is pretty tight as is. The fan has a 3/4" hole for the water pump with no adapter or spacer on it. That is why I use a Corvette pump which has a 3/4" fan pilot on it. The stock V8 Monza pump also has a 3/4" pilot unlike the standard smallblock pumps. By the way, my car did not have AC.......

Hi Clyde,
It's probably hard to see in the pics but my water pump, both sides of the spacer and my fan are all 3/4". Like I said in an earlier post my car was engineless when I got it and I'm only at the point where I have mocked up all my accessories (alt. and p/s pump) on my engine while it's sitting on an engine stand. I have checked and the fan will clear the pulleys, pumps etc with out the spacer and bolted directly onto the water pump. So I could fit it either way with or without the spacer depending on how much space I have between the fan and radiator. Since It has been over 30 years since I have seen a V8 monza engine bay and don't have any reference I would be very interested to know how much space you have between your radiator and the fan. Less than an inch? Also is your radiator a stock unit? How many cores? 2? 3? I appreciate any info you can give me, that I can use when put the engine in my car.

Well, when it comes to Monza's that had V8's, GM seems to have had many variations of brackets and pulleys depending what year it was and what accessories they were trying to drive. I was lucky to get a lot of my stuff from a guy that had converted a couple of V8 Monzas over to serpentine belt drive and electric fans. I think I have a mix of brackets and pulleys off AC cars, Smog pump cars and cars with just the Alt and P/S pump. It all seems to fit and work but I have some extra grooves in some of the pulleys that aren't getting used but I'm ok with that, as long as it fits and works. Honestly, if I knew how much stuff I was missing to fit the V8 back into this car I probably would have bailed and sold the car, but by the time I figured it out I had spent too much money getting this far to not follow it through to the end, plus up where I live you never see these on the road anymore. I might catch a glimpse of one every year or two, so it's sure to turn a few heads when I get it on the road. I would like to just get the drive line and brakes redone and get it back on the road as a Sunday driver and then deal with the paint and body later.

I got lucky finding this one everything was in the back of it from when they pulled the engine in 1985, The packrats got to it over the years and i need a lot of interior work they ate holes in the rear side panels and had a nice home filled with seat foam And carpet padding.... lol I did find a skeleton of one and it is big as a squirrel.
Thanks for all your input.
