I need some help, I have a 68 cutlass s convertible rocket 350. My question is, what is the correct tail lamp that goes on this car. I can't upload the photos from my Android phone. Is it the open end style or the split style? The split style is what's on the car but I have a newer set of the open style which I can put on if they are correct. Part number Guide 33 SAE STDB 68, OR Guide 34 SAE STDB 68.

 

The split style is correct. The open style is for Supreme and plain Cutlass.

 

Thanks yellow statue for the much needed help!
