318/340 main caps, new low price $95usd shipped
the bearings that were still on the caps, were marked 75 so, they are from a 1976 or earlier motor. also, from the rear rope seal that is still on number 5 main, these parts are from that era (1975) or earlier. i dont have the matching block to confirm.
after reading the info from others on this ad and comparing my caps that are for sale, to 340 caps i got on a 340 block, the mains i am selling would be from a 318, being slightly smaller in overall size. and , i think they would fit both a 318 or 340 without a problem.
