I bought this set for my '89 civilian car because I wanted the molded hoses to serve as a guide for which hose goes where. I disconnected all my old leaking hoses a while ago and couldn't remember how they were routed. The hoses all fit perfectly, maybe a little too long so it was tightly squeezed in one or two spots, but I didn't have to cut anything. Their overall diameter is thicker than the original hoses, so you can't use the OEM-supplied spring clamps. But on a 30 year old car you still have to replace the clamps. Also remember that if you are still using the heater core you will need to purchase another hose that is not included in this kit. However, Mishimoto packs it separately and costs about $20 on Amazon.
