I am planning on removing my 4.0L and rebuilding it but my cherry picker caster broke off. they had no replacements at harbor freight that worked and i cant find a brand name on the cherry picker anywhere. i am confused with the measurements for some that i found online. i measured it and measurements are:
top plate: 2/3/8''x3/3/4''
overall height: 4/1/2''
bolt spacing:5/8'' and then 2/1/2'' apart
bolt hole: 3/8''
wheel diameter: 3/1/2''
wheel width:1/1/8''
and its a swivel caster.
any other advice? i cant find any other place that deals with casters anywhere close to my house closer than two hours and i really don't wanna drive that far. Any help will be appreciated. i attached two pics of the cherry picker if that would help at all.

is there a tractor supply store near you? they usually have a good selection of cast metal castors.

Yeah there is a tractor supply company close to me. You think that's the best bet?

hard to say if it is the best bet, but it's worth a shot.
you may end up having to purchase two castors, one for each side.
won't matter if they're metal or those other softer wheeled ones.
