whats the difference in rebuild kits?

[srixon4406]

I'm looking at rebuilding the front end on the 62 VALIANT I installed KH disk brakes up front but it is my understanding the 67 to 72 drum and disk front end parts are the same. I'm I right with what I'm thinking or is there a difference in the two kits (drum,disk)
Please let me no

The only difference is the size of the bolt holes in the lower ball joint. They are two different part numbers, but the small holes have been successfully opened up by many folks.
