quick mopar distributer question

Hey magnumdust, how well did the limiter plate from fbo work out for you? i am considering doing this because its alot cheaper then dropping the coin for a new mopar distributer that has an adjustable mechanical advance. Another thought i had is, i see that don at fbo sells distributers as well and i was wondering, do you think i could call him and order a distributer and have him set the mechanical advance at like 18 t0 20 degrees and have him put springs in it that will make my advance all come in by 2800 to 3000 rpm? I dont see why he wouldnt set my distributer up the way i want it set up specially if im buying one brand new from him. But i am going to give the limiter plate more thought tonight. I'll be calling don at fbo tommarrow and i'll ask him if he would set a brand new distributer up the way i want it if i bought one from him, that way i could just drop it in and go because i know what i need to have. I need 15 to 18 degrees initial timing 32 degrees total timing all in by 2800 to 3000 rpm. If he would set me up with a brand new distributer ready to run out of the box with 14 degrees of mechanical advance so i could run up to 18 degrees initial if need be all in by 2800 to 3000 rpm i would buy it from him right then and there if he would do that. But i want to learn more about these limiter plates, how are they installed does anyone have some pictures as to how these limiter plates go in?
