The Hayden 2705 appears to be a STANDARD DUTY clutch which I prefer after going through 2 HEAVY DUTY clutches that made my 72 Cutlass sound like a school bus.
That fan size and shroud will work correctly. It will give you 3/4 inch clearance all around. It's been a while since I had a 69 small block, but I think I remember a 1-inch spacer between the water pump and fan clutch. You can check this visually when you have the parts the fan tip blades should be half in and half out of the shroud. Your motor mounts need to be in good condition.
If someone knows for sure if the 69 small blocks had a spacer with the HD fan and clutch, please verify.
The standard-duty fan clutch should work fine in your application since you are not running a/c.
When you look at the 772 fan you are going to purchase, it should have the curved blade tips on the end. This makes the fan less noisy and fits in the fan shroud better. I've seen repop 772's being sold without the curved tips, this is incorrect and may hit the shroud. Depending on variances in the vehicle or other issues, you may have to align the fan shroud by elongating screw holes. Saggy engine mounts may cause fan contact at the bottom of the shroud.
Top attachment has squared tips, lower attachment is original 772 and has the curved blades.

OK I do have new motor mounts about 4000 miles ago.

I use the original 772, 7 blade fan with the curved, round ends, with the hayden heavy duty fan clutch, and original fan shroud. I also use a Griffin aluminum radiator. This works very well in over 100 deg. heat with the air conditioning on full blast.

Yup. Even the TECH GUY at Jegs seemed puzzled by not finding the bolt circle dimensions. I kept pointing to this Forum as well as the one REVIEW that said it didn't fit.
So the problem is I need a 3.25 bolt circle and the fan from JEGS was 3.0.
I tell you this simple little project has been nothing but painful.
My next challenge is finding hardware.
I need 4 simple little bolts. 5/16-18 x 5/8 hex. Ace seems to go from 1/2 to 3/4 L. 3/4 is too long for clutch. 1/2 looks too short. Google.......Home Depot has them. 1 local store has 11. I order over internet rather than drive 10 miles, it was 99 yesterday, anyway order cancelled. None in stock. Today I'm working on the shroud. Only 96 and 15% feels like 90 LOL But I have the Fastenal store in my sights.....fir 4 bolts. Holes depth in clutch only a bit more than half inch. Or I'll use the long ones with an extra washer or 2.
The next step is determining what length spacer I may need for the clutch to water pump for perfect fan placement.
Then finding said spacer and hardware .
I bought my hardware from Ground Up. I don't have mine installed yet and won't need them for a while. If you're in a bind you could have mine and order new ones from Ground Up to replace them.
Here is a pic out of the assembly manual. You should be able to cross reference these part numbers. There is no spacer when the correct clutch assembly is used. I went with the standard duty clutch on my 68 AC car. Sorry about the pic being sideways. This site alters the IPhone picture orientation.
It started off a bit rocky and disappointing, but in the end, it came out really nice.<img src="http://www.chevelles.com/forums/images/smilies/thumbsup.gif" border="0" alt="" title="Thumbsup" class="inlineimg" /><img src="http://www.chevelles.com/forums/images/smilies/thumbsup.gif" border="0" alt="" title="Thumbsup" class="inlineimg" /><img src="http://www.chevelles.com/forums/images/smilies/thumbsup.gif" border="0" alt="" title="Thumbsup" class="inlineimg" />
