They switched to plastic bushings in ‘73 and later. The links above are of the ones you need. The mark-up on those bushings is strong. Usually Year One is the expensive one but they are less than half the price of Classic Industries in this case! $29 for one plastic bushing?!?! $12 for one plastic bushing?!?! This place sells them for $2 for the same bushing. And I think that’s $2CDN which is actually $1.50USD. I bought these bushings from National Moparts last year and they work.
