Bill,
I am presently winding up the RM charger, it is an excellent kit. only a few things to watch for. the forward end of the chassis has a small twist.
I checked several other kits I had, ...all the same. also check the
location of the rear axle in relation to the wheelwell cutouts...depending on tire/wheel selection the spacing may need some attention.
as far as front/rear valence panels..... I installed the rear panel before
chassis pan , and the front valence after the chassis.
I hope to have mine completed in time for kansas city.
