This is what the idler looks like, it has two bushings (see the grease fittings) this is the most comon problem with the 49-54 Chevy front ends ( the closer to spec this thing is the tighter the steering), both of the bushings need to be reamed in line....A reamer with a pilot is what should be used.... worst case is off to the machine shop the small end of a sbc connectiong rod uses a .928 finished size ( aftermarket bushed rod) so, I know we used to resize the new bushings after installing them.

What are the chances that any one local ( Newcastle to Pickering) has a .922 or .923 Reamer thats long enough to span approx 4"??

Im installing new bushings and a pin kit in my idler arm for the 54 chevy and need to size them after the bushings are pressed in.....

59/64 .9219 next common size  is 23.5 mm or .9252 what size is the pin ?

The pin is .921 and spec is 2 or 3 thou clearance.............59/64 would be the one or an adjustable one.............

I would think the pin is 59/64 unless they had it ground special . 23.5  would give you.0033 or .0016 per side fairly snug fit still trying to invision what part of the drag link is 4" . Honestly if you cant find one depending on how much it shrinks a 59/64 drill will get you enough clearance to fit it. may have to hit it with a flapper wheel quick . but Im sure someone will have it

If you want to bring it to Newcastle, I'll fix you up!! I have expanding reamers, and If that wont work we can bore it on the mill.

Edit;

I double checked to make sure I had that reamer, and I have it my hand. It will go from 27/32 (.844) to 15/16 (.9375)
