may work

 

BTW: it's for the '78 BRAT with lone-star air and sanden compressor

the old fan keeps breaking little bits off

 

 

how long do you watch the fan twirl?

Are you doing a restoration?

 

If not, I'd ditch that fan assembly and put in a second electric fan that won't fall apart as easily as those do.

I am in the beginning of a multi-year restoration

a/c works, fan stays

 

when done, I want it to look like you just stepped off the way back macnine set to 1979

If you want mine ill swap ya for an electric one in one of your crap wagons.

Over here 4wd EA81s got a standard belt driven fan
