I have a metric threaded Capstan winch drive dog which is now redundant as fitted 200tdi engine and needed longer thread arrangement.
Paid £50 for it only been used about 4 times anyone want to make me a reasonable offer before I put it on ebay .




Also have a HNJ drive dog bolt paid £18 for which was in my opinion too short for 200 engine ended up getting them to manufacture a 50mm long one.
