Drive shaft grease fitting size and type

[BGMachine]

Hi all,

I was greasing the driveshafts on my 80 the the front drive shaft grease/zerk fitting broke. The ball no longer seals and grease spits out. I tried replacing it with some fittings I got from the hardware store but they don’t want to thread in correctly. Does anyone know the type or size of these fittings? Better yet, an off the shelf part number? I’m assuming they have metric threads. Thanks!

Any auto parts store will have a small box of assorted zirks.

I'll try the stores down the street after work. hopefully they have metric fittings.

Ever figure out the size? My slip yolk zerk broke off on the rear ds.

@Kernal thank you good sir.

What I'm not sure about is if the zerk in the block for a U-joint (90416-06004) is replaceable and/or the same zerk as 96451-00600, just never had a reason to replace it.
