Radiator Support Washers

Re: Radiator Support Washers

Alex, just the exposed threads should not be painted...the nut should be painted. ARA

Ara,

Actually, it's the exposed threads along with the face of the hex portion. In fact, some of the flats on the hex portion usually wound up bare too.

The lower stud that you show in your picture and the stud Alex has on his car are for the 1968-69 A.I.R. mounting brace to attach to on big block cars. This stud used the same diameter through the hex and is longer then the earlier BB studs. The 68-69 studs were also mounted on the top drivers side position on the water pump as compared to the top passenger side on the earlier cars.

Mike, absolutely correct. I was more interested in making sure he knew that the whole stud wasn't devoid of paint...but that's right....just like the varying amounts of paint coverage on door latch's. Cheers....ARA

Re: Radiator Support Washers

One more thing that I noticed. The 66 AIM shows lock washers for all six bolts, two for the fan shroud and four for the radiator brackets. My 66 has lock washers on the center/fan shroud bracket but none on either radiator bracket.

I wonder if any engine compartment pic's of new 66 and 67's in the Adams book show the fat washers?

hi Michael,
here are a couple pics of my very original 66. mine is the same as yours with lock washers only in the middle
take care,

Re: Radiator Support Washers

Thank you. I did not paint the threads. I just painted the nut.

Looks good Kim. Unplated and just slightly larger than the thin washer that goes with it.

From what we've seen, when the thick washer is used on the outboard positions, the lock washer is not used.
