yep 73-80 style are straight
and 81-91 are twisted about 45*
need to know the vintage you need . as in year of the frame and bumper on the front .
I have a set of the '73-'80 ones.
From what I have seen, I believe that $75 shipped is a fair price.
I believe decent condition.
If you give me a day or two, I will blast them and see if they clean up nicely.
