Loosing antifreeze

Iv always wanted to do a Volare/Aspen sleeper with a 360. I drove a Aspen wagon for a while it ran really strong with a 318 it was alot of fun plus I could fit about 12 of my friends in that thing lol we had alot of fun Friday nights in that thing. My buddies called it the banana wagon cause it was this faded yellow color with "wood" trim.
