GT flares Fuch suggestion AND feeler gauge

[farleyd]

Hi everybody, if only i had had this forum in 87 with my first 914, it wouldnt have caught fire, and it would be in a junk yard...

Now, my first question :
i am about the ad GT Fiberglass flares on my 914. What is the size of the rims i should use to fill the flares considering I am gonna use 1 inche adapter/spacers (4to5 lug?

Second (simple enough):
whre can i get a feeler gauge for valve adjustment.

Thanks to all
