Check on LMC. THey're 20 bucks with cap. I used one on my old 67 gmc. The 74-80 one has ears on it to bolt it to the rad support.
I figured a newer one could be used,
I saw a set up at a shop that took up no underhood working room, it was cheap to make too.
just a piece of pvc pipe with a cap glued on the bottom and a drain plug/pecock and a cap on the top with a elbow barb fitting to hook the hose to.. and fits infront of the coresupport between the core and grill. it looked like it was 18-20" long silly simple, and it was painted black so it blended in and wasn't as noticeable.
