The one that came with my fan kit is adjustable & has a prod that goes in the top of the radiator between the fins. I have it on my 70 stepside. It works great. I believe it is available separatly from either Speedway or Summit. Is there a photo of your Grumman on the Gallery? I used to specialize in step vans. Worked on hundreds of Grumman & Union City's.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
