M38A1 Radiator Cap

Post by w30bob » Thu Apr 06, 2017 7:53 pm

HI guys,

Is the correct radiator cap for the A1 rated for 4 lbs or 7 lbs? I see conflicting info at different vendors. Also, I know the original caps didn't have a chain.........but we're they perfectly round or have 2 nubs or have 4 nubs?

Thanks,
Bob
