One for the 216 that measures 2 9/16" center of mounting holes. The other fits 235 that is 2 1516" Yours probably is the same as the 235 one.
They say money can't buy happiness. It can buy old Chevy trucks though. Same thing. 1972 Chevy c10 Cheyenne SuperIn the Gallery Forum | | | | | Joined: Jan 2016 Posts: 631 'Bolter | | 'Bolter Joined: Jan 2016 Posts: 631 | My GMC 228 is very close to the 2 9/16" c/c with 1.650 " bore.
I think the 228 and 248 use the same manifolds.
If memory serves me .....I think I used that insulator from classic parts.

Part # FS-106 They list the 235, 261 and GMC 302 as the same part with the 215/16" bolt spread 111/16 ID. Part # FS-238
