"Cool old Mack"
slatermichael0 (Galesburg,MI)
Its a good kit a lot of fun to build. I added some extra options from an accessory kit to mine. Pretty challenging for the most part not good for a beginner. Very detailed and very realistic looking replica. However some of the instructions are not clear as to what part goes where and some parts look nothing like what is pictured. The only thing I don't like is the hood hinges very difficult to put on and cannot get mine to stay on the grille or attach to the frame and make the good line up right So I made my own out of 3/16 brass rod.

"built the real thing"
I just bought this truck. I have bought about 30 other kits from HobbyLinc, and have just started working on them. Can't wait for my back ordered Revell auto trailer to come back to display my cars on. Bought this truck to use to haul the trailer.

Nice to see a few options included. Two exhaust choices, a stack or under truck and two fuel tank options of square or round. The rear wheels are retooled and a lot nicer than earlier issues. Nice to see the Matlack and Bard graphics too. Minus I would have liked to see the Alcoa wheels included, but not a big issue really. One thing I like personally is the bumper, fuel tanks, exhaust stack and a few other parts are NOT plated. That IMO opens up more options for the overall look.

"Great build"
This was a great model to build,my only complaint would be the amount of trimming I had to do


Due to small parts that could cause a choking hazard please kee away from children 3 years of age and younger.
