1999 Chevy Blazer Swapping cranks

both cranks should be identical..... i recommend sending both to a machine shop, and have them further matched up... also, while at the machine shop have your 95 crank turned, and order oversized rod/main bearings.... your this far into it, why use the old bearings you know??? turning the crank shouldnt be to expensive, and new bearings will be required.... also, have check into the bearings... its been a while so im not sure if your replacement bearings are oversized, or undersized.... tell your local parts dealer (i recommend NAPA) how many thousandths the crank was machined, and they will know what bearings you need.... hope this helps.
