CLOUDS of SMOKE!!!
The Smokey Base is from the Monogram "Super Fuzz" Kit. I needed to reduce the width by about 7/8", so I cut out a slice with a Dremel Tool & a Cut-Off Wheel. I hope they reissue this kit again, lot of nice parts here...
It is easy to cover the seam with a little putty...
The Tires fit into the base, Perfectly, just right for a Mock-Up!
