BIG, clunky, and crude, but, because it is BIG it allows one to really get into detailing. But there again, being of a large scale (1/16) kits to kit bash are few and far between , at least in the average builders stash.
Wheels are nice Cragar S/S mags. Tires, well John's "Snow tire" description , just about covers it.
The chassis, front and rear suspension lend themselves to fine detailing.As a mater of fact the front is very easy to make a working suspension if you can come up with a workable set of springs.I wound my own from some stretched sprue.
The engine and transmission , here again, not very realistic. You'll have to search for a donor kit.
So if ya gotta have BIG, you have your work cut out for you.
