What are you trying to accomplish here? Better braking? Just want it to look cool?
The early Daks were on a 5 lug pattern, but I'm not sure if everything will all switch over. Axles and drums might swap in the rear end if you find one with the pattern you are looking for. Which rear axle do you have? 8.25? 9.25?
What are we looking at for the front end? Is it a 4x4 or 2 wheel drive?
I've heard of guys doing a 5 lug conversion but it usually requires some modification of several components (redrilling rotors, modifying brake calipers, etc...) I personally wouldn't do this swap if that were the case. What happens when you're on the side of the road needing replacement parts and can't just get them from the parts store. Brake calipers might not be a big deal, but if it comes down to redrilling the hub assy then I'd never do it on my truck. I've had to replace CV axles twice and both times I was away from home with a limited tool kit. I would have been screwed if I had to modify stuff as well.
