Does anybody know of a source of long coach bolts of the cup square type? I require a couple of 3 inch bolts with a 3/16th thread and a cup square head.
I need these to repair the airconditioning condensor fans on my Rover SD1. The bolts are thoroughly rotten and have already sheared on one of the two replacement fans I have been trying to recondition. I would like to get some replacement bolts rather than try something else such as a length of stud with nuts either end.
It seems to be impossible to find anything other than metric bolts, and nothing of this length in anything less than M6, which is far too big!
Any lead much appreciated.
Michael
