57 idler arm

[jwtdvm]

got a question---my idler arm has a ball bearing type bushing set up--not sure if original or after-market--even has grease fitting in the top of the set up--my question is cotter pin placement--there is only one hole in the bushing and the grease fitting is in the center so pin couldnt go straight across to another hole anyway--Am I supposed to somehow get the pin thru the hole and spread around the grease fitting and have it curve back on itself??--seems tough to do in the car with engine in place--am I missing something??

The 57 idler has an acme thread that it pivots on,so a ball bearing is not factory.
