Could you please tell me if parts for a 1974 VW Beetle 1500 are compatable with a 1970 1500 beetle please?

They didnt make 74 1500s maybe its a 1300 ???

what bits do you need to know about ???

Hi, just looking at purchasing a 1974 Beetle with a reconditioned 1500 motor. Apparently he has various spare parts for Sale (will know what exactly this afternoon) with it & My Mum currently has a 1970 1500 & we're thinking we could maybe use the parts on hers to fix it up a bit.
