I have a F350 and my filler plug on my rear differential is stripped and I need a new one, I have been calling around and can't find one anywhere. Does anybody know where I can buy one or is there a universal one I can get somewhere?

 

The plug on my GMC was stripped...It was a pipe thread plug, forgot the size, but I would imagine yours is a pipe thread too......any plumbing place should have it

 

Thanks, I'll check it out
