I have a 66 442 hardtop. I just bought new door jamb bumpers from Speedway Motors for it. They sent bumpers that say they fit 63 Chevy. I went to Fusicks web site and found the ones which are exactly like what is in my car now but they say it fits 67 Cutlass. The ones they show which are correct for a 66 are like the ones Speedway sent. These bumpers are split lengthwise. Does my car have the right ones in it now or are the split ones correct? Thanks.
