[old gh bug]

Hi i have just found this site its Brilliant i have been reading a lot of the threads about 944 brake fitment and i am getting confused (not hard)
I have just bought some 944n/a brakes full lot of a 1984 model

i have no problem with the rears but its the fronts i am confusedwith

i understand the spacer for the outer bearing thats ok but when it come to machining the front hub that is where i get lost

what do ihave to do i have read and looked at drawings on here

i have std disc b/j spindles and would like to to keep to as close the same track width as possible

How much do i need to take off the hubs etc do i use the porsche bearings still or can i use beetle ones

any help would be much appreciated
