I installed new GM headlamp buckets in my 70ss. All the headlamps will fit but three of them have to be rotated 90 degrees to get the tabs to sit int the buckets correctly. I checked the year one catalog to make sure I put them the buckets in the right locations. Besides, looking wierd the halogen headlamps don't shine properly rotated. The headlamps are ones that I just picked up at the local parts store ( sylvania - I think). Anyone else have this problem. I'm wondering if its the lamps that aren't right and I should buy y the GM's. I don't want to pay for the T3's. I guess another option would be to cut new notches in the buckets. Suggestions?
