944 Front brakes on a 68 beetle help!
 

I would like to put the front brakes from a 944 on my 68 beetle. What do I have to do. I have the rotors,calipers. I bought new dropped spindles from cb performance. I noticed that the caliper will almost mount. But what about the bearings. What do I use. How much do I machine off of the back of the hub? I have read a lot of the info on the forum and am thoroughly confused now! So help please Thanks in advance.
