In the original post about this kit, I did a comparison with an original Mod Rod, and I only seen three parts missing, the grille shell, the clear "bullits" for the grille, and the bed cover. As Mark mentions above the fender unit was modified in the running board area, and the hump on the cowl has been removed. As a big fan of the original Ala-Kart kit I have every original version of all the kits that have the Ala-kart in them. It's pretty cool that round 2 used the last version of the Mod Rod kit, and the last kit to have the Ala-Kart option. It's kinda sad that R2 didn't see fit to at least go a tad bit further to bring back the last few parts, and fix the body mods, but I was disappointed When the '50 Ford didn't have all the original parts back in it! Update: Today I spent a little more time comparing the new kit, against an original, and found a few more missing pieces. Most, of the A-K side exhaust is missing, I say most because there is about an 1 1/4" of one side still on the tree! The main exhaust is missing a 1/4" section w/ 90 degee bend, and the injectors are gone, the valley cover is still there.
