6 lug rotors on 71-87 c10 spindles

[Daniel 61 Apache]

First I just wanna say that this forum is awesome! I sometimes have to pry myself from the computer cause I can't stop reading! Right now I'm in the middle of doing a disc brake conversion on my 61 C10. I've got a cross member out of a 85 C10 with the 1 1/4" rotors as required. I'm keeping 6 lug wheels but was wanting to make sure that the 6 lug rotors I buy will work on the 85 C10 drop spindles.

So, has anyone bought 6 lug rotors and put them on a spindle from a 73-87 C10 spindle for your disc swap?

These are the two websites that have the 6 lug rotor for sale. I like the CPP rotors cause for some reason they are $50 cheaper for two.

CP4R6 6-lug Disc Brake Rotors, pair for $129.00 from Classic Performance

and

60-70 C-10 6 lug (1 1/4 thick) $89.00 each from Early Classic
