roller rockers / springs for headrests

I have a set of crane gold 1.6 roller rockers, single springs w/dampners and factory shafts for an RB motor. All parts in very good condition, missing 5 adjustment studs ... do not know the spring rate of the valve springs, but i do know they were matched with the 1.6 rockers. Also have a set of used factory rocker shafts, straight, not warped or grooved. Not sure of an asking price, but i need a set of headrests for my 1970 dart, bench seat, black ! If somebody wants to buy a set from classic industries or year one, i will trade straight up. I think this is a fair deal ! headrests can be bought for under $300 ... Erik ...
