[Already Gone]

I installed a front 1 1/4 inch bar from a 79 Chev 3/4 ton 8400 GVW "Trailering Special" pickup on my 72 BB longbox . The sway bar made such a difference in my truck that I want to get a rear one now. After reading this thread I went to my local wrecker to find an IROC and get the rear bar. I didnt find any IROCS but as I was wandering the yard I started to think that maybe the truck I got the front bar off with the "Trailering Package" may have a rear bar. I found the truck again and looked under it and yes it does have a rear factory bar. What do you think guys, will this bar work on my 72 long box? The biggest difference is the leaf versus coil suspension. I think I will go and get it this week and if it wont work for me one of the guys with a 73/87 can probably use it.
