I have 2 black AMC lap belts for sale. Not sure which models they originally came from. I installed them in the back seats of my Javelin and Spirit to haul 3 kids when they were small. Model No. 379429 has the silver release and Model No. 472855 has the black release. $20 each plus shipping. Contact Gary at firstname.lastname@example.org or (920) 731-0119.
