Not sure which size I have. I ordered a cam kit years ago with guideplates from cmotorsports. Well, I need to replace the guideplates because they dont align up right, I'll be going with trickflows. My problem is I'm not sure which size studs I have. I'm running comp pro mag 1.6rr's. Are these made specifically for 7/16 rocker studs or can you order them for 3/8's too. I just dont want to order the 7/16 rocker studs to find out I already have them installed on the car. thx for the help.

 

Take a stud out and look at it. The bottom of the studs are always 7/16. So, if the top looks smaller....
