Working on a '69 Super Bee 383. Have had a Mopar Performance Viscous Drive fan in the box for a while, wanted to install it. It won't fit. There is not enough clearance between the fan and the radiator. I checked my radiator #'s and it is the original, correct radiator. I also bought a shroud and brackets for the shroud, and it fabs up like it is supposed to. Looked through my service manual and can't figure out anything from it. Do I have the wrong fan? My part# is P4120758, and I can't find another one listed. The water pumps are all the same as far as length goes, so I'm wondering what I'm doing wrong.

you didn't do anything wrong, nobody makes a correct clutch i have a 68 rr 383 and had to use a 89 jaguar clutch someone will chime in on the correct # you have to use the bushing thats included, on my demon 340 i used a clutch for a 79 sunbird 305 engine and it fit but it was a bit to long for the RR

Strange that Mopar would sell a fan upgrade that won't fit.

They dont fit, and neither does a parts store replacement.
They will probably fit the E body style cars..

There is a replacement clutch that does fit, it is just not listed for 68-70 Mopars....

Mopar replacement fan clutch = 3.65" tall
Hayden part #2765 fan clutch = 2.58" tall
The only downside is that the hub holes are slotted.

Good luck,
Bob

Thanks, with a part # I can probably fix it. I had one on my first Super Bee that I bought in '69 so I know that at one time they made the correct ones. Why don't they make them now?

This has got me thinking now. I was thinking of installing a viscous fan on my 383. Will I have a problem finding one that fits?

I forgot to add that I see a viscous fan package in the Paddock catalog. It includes fan, clutch and hardware. Shouldn't this fit alright?

didnt fit my 66 newport

Fit on my '69 RR 383 and 440 upgrade

I had a thought yesterday about this problem, and that led me to my "spare parts pile" near my garage, the one my wife says I gotta clean up. I found 2 fans and viscous drive clutches that I had removed from a couple of engines that I bought last year. On one of them from a 440 the drive was identical to the Mopar replacement. It was also the same length. I found another that came off of a '72 400, and it was shorter by 3/4" and had different markings. It must be a Hayden, because as Radiatorman reported, the holes were slotted. It worked fine, fit is just right. Soon as I clean it up a little it will be ready to go. Only difference I saw was the bolt holes for the fan weren't as deep as the Mopar fan clutch. Oh yeah, I couldn't wait to tell the Warden that having that pile of junk saved me some money. If I could find a pair of earrings out there I will be good for another year.

The Hayden clutch fan works fine..
Our solution was to shop for a TRW FC28, this was a short height (2 3/4") Mopar replacement part. Also it had the 4 holes rather than the universal slots. Check out some of the swap meets thats where we found ours, still in the OE box...

Just my $0.015...

Years ago, aboiut 1997, I got the MP kit and it fit a 69 RR no problem. That car had a 22 inch rad.

some may fit if its still a stock 2 core, but when going to a 3 or 4 core that when the problems start.

Shortest Mopar clutch you will find,2 1/4".

Although yours is shorter than mine(couldn't resist) that is the less desireable torque limiting clutch, the 2965 is a thermal. Just some info incase you didn't know.

I put the Mopar P4120758 viscous fan package on my '69 Bee (383, 22" radiator - after market 3 row) with no problems. Fan # is 4140063. The clutch is 1/2" from the radiator, the fan blades are 1" from the radiator.
