I needed to purchase the Rear Bumper Bar ‘Special’ Bolts, Part No. C1991 but couldn’t find any so we had 50 made by an engineering firm here in Melbourne using a drawing from Allan Crouch with input from Alan Gibbins. Ivan Stevens had them made from polished stainless steel so no need to chrome them. They are tightened with an Allen Key as per the original. Alan Gibbins has seen the finished product and given them his ‘tick’ of approval. If people need to replace theirs then please make contact with me. They are $20.00AUD each + Post to wherever you are. The red ‘Reflecta’ stud is mine only for comparison and display, sorry. Barretts are trying to find a manufacturer of the studs at the moment, so fingers crossed!
