Morris Minor Owners Club

I've just ordered a new lower fulcrum pin from ESM and notice that one thread end seems slightly longer - maybe 5mm - than the other - is this normal? If so, does longer end go at front or rear when looking at the lower trunnion? Also, please can someone confirm right thread for the corresponding nuts?

Many thanks

Long bit to the rear. Should be supplied with nuts and washers

Thanks, strangely enough nuts and washers were not included.

Thread 5/16 but I've seen both UNF and UNC variants!
