Craig’s CJ-3B “The Mutt” and FlatFender Willys

Craig’s CJ-3B has been a regular visitor at Sam’s Flatfender Willys shop in Arvada, Colorado, where Craig has allowed Sam to experiment and update his jeep in a variety of ways.

Sam’s not some  shade-tree jeep mechanic; instead, he brings 45 years of experience owning, running and working in hotrod shops in California. One of the early projects he worked on was the famous Munster Mobile.  Sam tried retiring, but that didn’t work for him, so when he moved to Colorado years ago he started buying jeeps for himself and rebuilding others.

It doesn’t take long when talking with Sam until you realize that he has a lot of ideas, and they all seem to be good ones. So, I am not too surprised that folks in the Colorado area keep him plenty busy restoring, updating and servicing their old jeeps. If you want to contact Sam and talk with him about your jeep, you can email him at or call him at 720-841-0614.  His shop rates are very reasonable.

As I mentioned, Sam has done a variety of changes to Craig’s jeep, including a rack and pinion system, an emergency brake, a lift, and a complete rewire.  This time Sam volunteered to give Craig an inexpensive floor pan a rebuild.

Here are the old pics:

In the image below the arrow points to a rubber line.  Replacing that was a priority for Sam.

Front floor removed and replaced . Dark Brown is new floor and black is removable two piece front and rear panels for access to transmission. NOTE: the arrow points to the new STEEL fuel line.

A shot of the complete Mutt.  When it came time to paint it, Sam was ready, but Craig wasn’t.  He said he wanted it to look like a Mutt, so he is keeping the mismatched colors like they are for now.

Here is the trailer that Sam built for the Mutt.  There are more images of the trailer here.
