Hey guys, I have been wondering when exactly whoulder belts because standard or opional for the matter. The readon... My '68 roadrunner that I'm restoring had just lap belts, BUT it has the clips on the sun visor mounts to hold the shoulder belts up and out of the way. Also, the welded nut is in the roof support, but the headliner was never cut for it (looks to be orig.) and no belts present. Were they optional in '68 and standard in 69? I'm just wondering if my car is a mess up or not. Thanks.
