you could braze the end of a std bolt after grinding head to the right thickness,though lr just used a thin headed boltlooks like no cam button for me then
"The Teflon Thrust Bolts are not suitable for early Rover V8 engines as the cam bolt thread rate is imperial and not metric. Suggest consider installing a thrust plate and machinig the cam and block to accept as per the post 1995 engines "
I dont fancy drilling and tapping my nice clean oily engine at this stage lol
Noisy I though you bought an early rv8 when you did yours, but you fitted the button didnt you?
its a camtech one from aus, I will try the bolt when I get a chance lol
