From 74 up all the necks were the same length. So all forks with the trees from 74 up swap.
The 74 -76 were 34 mm forks and used the two piston calipers. The 77 up were 35 mm forks and used the single piston calipers.
The 76 used a two piece disc brake rotor, The 79 used a single piece disc brake rotor. The two piece disc has more offset to work with the two piston caliper. About .2 inch.
So putting the 79 forks on your 76 you need to use a 77 up disc brake rotor. These work with the single piston caliper.

Okay thanks i have a 76 that i already hard tailed but i just found a good 79 that is complete running factory bike for $500 and i was going to use the forks wheels breaks pretty much everything from the 79 although my 76 has a 1 piece rotor and single piston caliper. Thanks Leo i have been waiting to afford parts i need everything except the frame and motor and when i found this bike for 500 and it is complete and running i jumped on it.
If your 76 has a one piece rotor and a single piston caliper then it must have a 77 up fork on it. The bolt spacing for the calipers is different and won't swap.
Unless you have built an adapter plate so the later caliper will mount on the earlier forks.

Well that being the case I would just use the 79 forks and triples breaks and wheels then it should all work together if the triples/forks will bolt on the 76 neck. thanks Leo this is my first bike outside of dirt bikes so I learning from you guy's.
