To serve an entirely different (non-Triple M related) purpose I am searching for one fork with a 1/4" BSF internal thread and the corresponding lug threaded 5/16" BSF which bolts to the firewall upright.
I realise that new ones are available but I would prefer something well-patinated.
Andrew I may have one in my box of bits. It must be from a rebuild 50 years ago. Cannot replicate the patina, as I think it was cad plated with many other parts when I had free access to a plating plant. Will look tomorrow Allan
Andrew. I have found a fitting which has a fork which is tapped 1/4 BSF. The other hole has a 3/16th inch bolt so may be from a SU linkage. The fitting is unused cad plated but the stud is close to 1/4 inch X 3/8th inch long but not BSF, perhaps 1/4" UNF. The fork and bracket fit well in the slot, but would need a small amount to fettling to get the hole centres inline. Let me know if it is of any use. Allan
