Connecting rod caps on my 1959 5.5 hp (cd-16)

[DaffyJeffy]

So I'm rebuilding a 1959 Johnson 5.5. I'm in the process of reassembly right now and I'm annoyed with the flat head-style rod caps because I can't put a torque wrench on them to set the proper torque (60-66 inch pounds). I have them snugged up real good with a large flat head screwdriver assisted with a small wrench on it's square shank. How critical is this torque setting?

I'd say pretty critical. I use a flat-bladed screwdriver socket on my torque wrench. You probably got them good enough with your method. Hard to say...

Do as F-R suggested. You can buy them at any parts house.
