a rotor swap question

[tonypaul]

I read most of this thread a week or so ago while searching for info on some new rims for my truck. And forgive me if this was brought up already and I missed this info.

My truck still has the drum brakes up front which has to go. I found this : http://www.ecklerstrucks.com/product...3&dept_id=1035

Would this solve the problem to get these wheels to fit, by changing the rotor to a different bolt pattern?

Two days ago I purchased a whole suspension clip out of a 1980 5/8 ton truck, with plans to swap it over to over to my 68 GMC swb. I putting in a
8.1L (vortec496) with the 4t80e and thought this would be better for the extra weight I will be carrying now. So, does anyone know if a rotor from a chevelle (like in the above link) will just slide on the 5/8's spindle and give me the 4.75 bolt pattern Im wanting?

The reason Im doing this mainly is that Im putting in my beefed up `10 bolt
s10 rear axle to give me a tubbed look.
Thanks in advance for you input on this situation.....
