37 ford steering box fill plug

[shuffster]

Just replaced all internals -parts from Mac's. I also needed a new cover and replaced it as well. Old cover was handmade. Question/ What is the filler plug size? Mac's didn't know and doesn't have. I thought it was to be pipe threads, but appears to be 3/4 x 20 TPI?? and I cannot find one anywhere. Oring boss plug is close, but is 16 TPI.

Also, Mac doesn't have the special washer that is assembled with the adjusting screw--fits in the sector groves- anyone with dimensions on this?

New worm and sector roller really make this box feel good.

thanks for any help you can provide.

B-3538 is stamped and looks like a mini 33 front hub dust cover . I have an extra . Dunno what the thread is but it's tapered and pretty fine . David J
