Rear brake bleeder screw

[memo43]

So I recently decided to do some R&R on my rear brakes.
(New center rubber hose, new wheel cylinder, brake shoes and hardware.)
Mostly due to me never servicing them since I've had the truck.
Its an 1985 Chevy k20 3/4 with 13 inch drum 2.5" brake shoes.

Now for the life of me I cannot find the part number for the "Speed Bleeder" for the rear, I have them for the front.
I want to eventually replace the front rubber hoses along with the brake calipers along with the MC.

There is nothing really wrong with the brake system, but I figured if i have to replace one part and it affects the rest, why not do it all and put it under the "MAW" category
Might As Well.

I'm hoping some one has switched to the speed bleeders for the rear and has the part # handy.

Thanks in advance
