[rodstored-72]

hey guys & gals,
i am trying to put the front end back together on my '72 chevy 2wd truck. i can't remember how the pass. side horn assy. is mounted t othe firewall?? i am able t omount the driver's side horn, but i don't seem to see a bolt hole on the pass. side.

could any of you give me directions on where the horn is mounted???

oohh yea! i also am trying to put the radiator back in & when i bought the truck the lower radi. supports were not installed so could someone tell me how you "install" the lower radi. support mounts on my '72 chevy 2wd 1/2 ton pickup??
