We just started a similar thread on throttle response. Do you have a first Gen 8cyl Firebird? Found your answer interesting....are you referring to the plastic bushing/retainer 403929 shown here: https://www.ebay.com/itm/NOS-1966-1979-Chevelle-Camaro-Firebird-Toronado-accel-cable-retainer-403929/323050967801?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160908105057%26meid%3D5ab0023f8d2c4ab89db13898ad68fcb8%26pid%3D100675%26rk%3D6%26rkt%3D15%26sd%3D351434061297%26itm%3D323050967801&_trksid=p2481888.c100675.m4236&_trkparms=pageci%3Ab03c351c-aecb-11e8-8433-74dbd180db3d%7Cparentrq%3A9b132a8b1650aa15b389df37fff8bdda%7Ciid%3A1
My reason for asking, a few of us did a quick research on this retainer and found it was only used on 6cyl and 70-72 years. If you could give an update/confirmation would be appreciated.
