I mounted an 89 front clip on a 79 blazer everything bolted together except the hood hinges, which is easy enough we just cut out on the firewall with the plasma cutter. i still have the old windshield wipers on it. they work as long as you dont install the filler panel from the hood to windshield. but your doing opposite going to older style front end should be easier. should all bolt together and the hinges mount on the fenders so it shouldnt be a problem. might have to install shorter windshield from older truck, but it might clear the hood. try and see.
