Speedy engine big end bolts

[Colin Wilks]

I am resurrecting this thread as Steve's initial query is exactly the problem I have. I am fitting a 1 1/2" John Barlow crank and reusing my original Austin rods (which have the green light from Nick Turley). I am not going to reuse the big end bolts which I am sure have been torqued up on several previous occasions so am wanting a set of bolts as in Steve's photograph. As he says these have a pin perpendicular to the shaft to locate the chamfer and have much meatier heads than the chamfered but pinless jobs which I think may still be available, but which are probably not robust enough to drill and pin.

Has anybody found a supply of these bolts and if not what cunning alternatives can people suggest?
