I'm working on a 1970 350 buick while cleaning it up, I seen these round plastic pieces in between the bridges. They kinda make me think they align the bridges. Well, Anyway I'm missing like 5 will this be a problem If so where should I begin to look for them and what are they called o No: I've also seen that the bridges with them missing shake alittle. PLEASE HELP uzzled:
Are you refering to the round plastic buttons on the rocker arms? TA Performance sells replacements. Inexpensive too.
