Here's a link to the kit history I did for the 67-72 GM pickup line: http://www.modelcarsmag.com/forums/index.php?showtopic=69861
With the way Round 2 works these days, it is hard to say when/if they will reissue the 72 Fleetside. I would love to see them pull out all the extra tooling bits and include the tow truck and fire truck options.
I have a Model King-boxed 69 GTO funny car and a buddy of mine has the later Round 2 issued kit and both had the same slicks in them: one Goodyear, one Racemaster. I have a feeling someone mis-matched the mold inserts.
I agree with Darrin; I love a lot of the subjects MPC produced. Sometimes the kits aren't up to modern standards but the subjects are what is the best.
As a warning, however, the Lonestar's initial instructions were absolute garbage. The subsequent Hudson and Chrysler 300 instructions are great. If you pick up a Lonestar do yourself a favour and download the Revell Germany instructions from their website.
I believe Blue Oval Resin Works had a whole bunch of resin items for this body style truck, including all the different grilles, corrected 8' bed, a 6.5' bed, crew cab, visors, etc etc. No idea if he is still producing these, however.
