https://kansascity.craigslist.org/pts/d/shawnee-mission-rear-end/6787246187.html Is it true this will fit GM 64-72?
It looks like it is a 66-68 era. If so,it is the wider rear. The BOP rears were only narrower for 64-65. Some leftovers were carried over to early 66’s,but that is not one of them. The earlier ones also had the flat spring perches.
