I had 4 , now have one, can anyone tell me the thread for the 1912 and 1913 ( early ) heinze coil box, it seems that this thread is neither fine nor course.
Any info leading to the threads OR IF ANYONE HAS THREE OF THE BIG HEAD HEINZE WOOD COIL BOX TO FIREWALL NUTS, l'd be great full.
David, they are 5/16-20. It's a special thread. Check with R.V. Anderson, he may have them.
David, RV does have them on his price sheet, they are 19/64 not 5/16.
Thanks Kim, 19/64 20 thread..... perfect.
RV's email address bounced back as an error ??
RV are you there ???
Can l have 4 nuts please.
