Looks like 79 has 35mm forks so it should be a direct swap on the front end, but I just rebuilt my forks and had the lowers powder coated black so idk about trading entire front ends. Just swapping wheels is tricky because the brake is different between sohc and dohc models. You can bring it over tho, and we can figure something out. I have access to a lathe and mill and I'm a damn good machinist
