Can anyone please clarify exactly which size thread are the front suspension lower grease nipples on a 1971 4/4 4 seater?
So far, it seems it's been suggested that they are: 1/8" BSP, 1/4" UNF OR 1/4" BSF.
Can anyone say for sure which is correct, before I start the next quest, which is where to source them locally, in West Yorkshire.
Many thanks
