as a B/MP race car, there was not a lot of "trick" allowed....other than Butch Leal and one of his former Pro Stock Hemis. The Butler chassis is complete as originally built other than rear coil overs were added somewhere along the way. Everything to return the suspension to the as built leaf springs / ladder bars is intact....right down to the original pads on the original Dana and ladder bars. The trickest pieces I see are the rear forward strut bars that tie the chassis to the front of the ladder bar mounts. The way the rear frame rails are sectioned / narrowed along with the mounting of the front spring hangers are a work of art.
Our original thought was to bring it with my HDK mock-up Hemi to the Nats, but I have since decided to get to work on the re-hab instead.....and once I tear into it, I do want to half way re-build it for a car show.
