are there any kind of adapters that can change my bolt pattern to the gsl-se pattern, and if so where can I buy them?

 

They are called Coyote... I've heard of them once, and they will change your 4 x 100 to a 4 x 114.3

 

There are tons of people on e-bay that will make you custom adapters for any application that you want. I have a set of 1.25" thick, 6061-T6 aluminum hub-centric adapters coming to my door anytime. Got them through an e-bay auction for $160 shipped. I had them change my 4x110 to 4x114.3 (4.5 inches). There are all kinds of wheels for this pattern. I cant believe all the choices now. I'll post pics of my adapters when they arrive.
