Brake bleed screws

[bugedd]

Can someone tell me if the brake bleeders on the rear drum brakes (stock) on a bugeye and the front bleeders on a disc conversion are the same thread? I want to get some EZ bleeders for when I replace my master, but need to know the thread pitch first. Thanks in advance.

Go here and he lists the sizes of the bleeders in his ads or you can just order from him. https://stores.ebay.com/Kirbys-Brake-Blee...d=p4634.c0.m322

From my Spridgets file:

Speed bleeder sizes:
Clutch (all spridgets) 3/8 x 24
Disc brakes 3/8 x 24 front drum brakes 3/8 x 24
Rear brakes (1 piston 1/4 leaf springs) 3/8 x 24
Rear brakes (2 piston wheel cylinder, semi eliptical leaf springs) 1/4 x 28
Found some at an Advance Auto, Dorman Help! brand, part #12701 (carried by others, like AutoZone I think) These fit my slave and should fit the front calipers. 2 for $10. I popped one in the slave, clear hose to bottle, pumped the pedal, watched a few air bubbles fly through, then nothing.

PS instead of a 7/16" wrench to turn, it's a 3/8". So I put one in my vise and bent it so I can turn through the access hole.

An addendum to Jim's post. Newly made cylinders for the rear are likely metric.
