I have a 1st gen obd0 b16 with CTR intake cam and GSR exhaust cam. I finally tracked down my CLICK-CLACK to the LMA's. Instead of buying the B16 ones which a more expensive I'm gonna go with the H22 lma's. I know a 0.040 spacer/shim is required for these to work properly, but where do I get it? If anyone knows where a "how to" on doing this is, it would be amazing. Any info would be helpful, thanks.
