Old First Gen Ladder Bars

[brymek]

First off new to here, thanks for letting me join.I have a 69 Firebird I just finished restoring, my father and uncle built it in the late 70's early 80's. I've had the car now 25 years, I figured someone here would know what these are. Trying to identify these ladder bars Lakewood/NMW???? Can't find anything listed from Lakewood for 67-69 so I'm curious. Any insight would be appreciated.
