need help with fitment VW mk3

[domscanga]

Been thinking about running vintage 15" mercedes hucaps for awhile now and need help with fitment. I will be switching to 5 bolt up front since right now my fronts are 4x100 and rears are 5x100

-The steel wheels I found are mk4 steels which are 15x7 et 38

-I am running mk2 axles,etc up front so its tucked in more than rears

My current wheel setup are mercedes s class wheels 16x7.5 et 51 wrapped in 205/40s

Adaptor setup

Rear
26mm adapter
5x100 to 5x112
CB:57.1 Vehicle only.

Front
35mm adapter
4x100 to 5x112
Vehicle CB: 57.1
Wheel CB: 66.6

id like fitment to be as close to this with running 195/50/15 tires. do i need to run spacers?

thanks in advance!
