I just purchased a whole set from mancini, If your engine is orginial then the engine had 1.5 rockers. You need to know if its the right or left one that needs replaced because they are different. You can also buy them individually. If I had one go bad, I would change the whole set.

Summit has some either aluminum or steel. Some have a 1.5 ratio and some have 1.6 ratio. Not sure what the difference is and if either would work. Is there any other source for these? Thanks in advance for any help. Dave ---- Please address private mail -- mail of interest to only one person -- directly to that person.
