Ah! There's part of the issue.

If you look at your brackets for the p/s there are spacers between the brackets themselves. Looking at Dave's picture the brackets come together flush. If you remove those spacers that will move the pump forward and get the belt away from the bolt head properly.

That will also move the belt forward one sheave and require you to move the alternator back to where it is supposed to be. A double sheave (at least) water pump pulley is probably in order as well.

When I did the truck (it's a 69 Cougar motor so it's relevant right?) I ended up getting the kit with both pulleys in and got the 3 sheave water pump pulley at their recommendation. The belt doesn't really contact the water pump enough to drive it or anything when tensioned but they recommended it to help guide things and keep them from slapping together in the event something goes awry.
Just my $.02

I verified that it was indeed a 4-bolt crank, and I pulled the spacer out of the power steering bracket to see if anything would line up with it in the correct space, but no luck.

I also found this nut welded onto a bracket bolted to the block behind the power steering bracket. Is that correct or do I need to order some sort of piece to replace that to put this all back together correctly?

Looks like I'm going to need both the crank and water pump pulleys from CVF as well as the AC and idler pulley brackets. This issue is definitely hard on the budget.

While I have the crank pulleys off is there any reason to replace the harmonic balancer or are those generally good forever? I do have an issue with my timing marks not showing up anywhere near the pointer, but I'm thinking it's probably easier use timing tape to remark it than to swap it.

That welded nut contraption is definitely home made.

Exactly the issues I ran into with the truck. Swapping to an older style balancer and pulleys would also get everything lined up, but I was not convinced I could put the right combination together. Maybe someone here has a set that they know works together that would work for you.

They do of course wear/age as the rubber gets old and more brittle. The ring can slip causing the timing marks to not line up as you described, however I'll bet you have the newer balancer with the older pointer location thus giving you no marks where you expect them.


I'm curious about the alternator here too, it looks pretty far forward. Is it bolted in front of its brackets instead of behind them ?

Once you get the right crank pulley on you'll be amazed at how well things suddenly line up.

The alternator is behind the bracket and bolts up with what I assume is the original spacer behind it.

However, now I'm kind of worried as to whether or not any of the brackets are correct. I'll have to see what numbers are stamped on them.

I guess the foolproof solution is to order the pulley and bracket kit from CVF, and just replace it all with their system, but at that point I can probably find a 289 around to swap back in for around the same price.

A similar bracket to the one on your engine is found on 351W engines to hold the alt and/or P/S systems.

Ok, I just verified that it's a 1974 alternator bracket, so that's wrong too.

I'm now up to replacing the following:
- Crank pulley
- Water pump pulley
- Alternator bracket
- AC bracket
- AC idler pulley and bracket

The cost is getting high enough that I'm really leaning towards just going with a serpentine conversion kit at this point.

You don't need brand new, see if someone has a set they are willing to sell you. Are you putting the A/C back in with the stock system? If so, then you will want to get all of it for that application.

Yes, I'm planning to add air-conditioning back in and fix this all at once.

After much research and deliberation, I ordered the CVF serpentine conversion kit. Fingers crossed that it goes on easily and solves all my issues.
