Big end nuts

[Howard Wright]

Thanks Chris and Hugh

I don’t have the original bolts but by looking at the rod they were round head located by a pin under the head.  Standard A7 bolts won’t fit as they are located by a ridge on the rod and aren’t long enough. I don’t rate my chances at finding new Nippy bolts.

Chris I like the idea of bolting up into a Helicoil but as you surmise there is not a lot of meat because the side of the rod and cap is scalloped.

Cheers

Howard
