Yeah, OK, so I was backwards. For some reason I was thinking fine, not course. Oh, well, he would have figured it out, can't do everything to jog your memory, can I?
Dave take spares,  Factory is a split washer.  As long as the bolts don't hit the water pump, anything will work.  The longer, the longer it takes to tighten.  You only need about 1/2 and inch on the inside of the pully

Well I have a range of lengths available, so I thought I'd try and get right ones the first time....  Sending fan to powder coaters to get blasted and coated black.  20 bucks. Pays to have businesses like that leasing space from my employer.

Fan works well, looks nice!  Had to make a little clearance down low.  Blades would barely touch bottom tank lip under accleration, just a touch.  Fan is a lot closer to the rad now.

I had that problem with the 62 also.  The safts on the clutches are too long.  Those fans are generic, and mostly for small block mopars.  I ended up with a high quality flex fan.

Isn't that an oxymoron?

As long as you can get a pencil between the tips and the shroud, you have enough clearance to be safe.

Shroud?  What's a shroud?

Adjust it so it doesn't hit the bottom tank. I thought it was tuoching a shroud "just a tiny bit", which, within a short period of time, will eat through the water tank. Figure out exactly where it is touching and either shorten the spacer, which is a lot easier than trying to cut the tips of all those blades. I don't think you can move the radiator down, or out, to clear the tank.

It's adjusted and no longer touching anything.  It has no spacer on it at all.

Boy Ed that's pretty tight.  I was taught the thumb rule on that

3/8ths inch is enough to allow safe clearance, but metal on metal is not good over time, it will wear out the copper tank and start leaking. I don't know how much the spacer needs to be shortened in order to give this minimum clearance, flat sanding may be a little hard to do unless you have a sanding belt where he can hold it square and shorten it. Mill or lathe cut would be the best/right way to do it.
