I'll take some pics at some point but this is the buck from my MGB roadster build.
Working height is 30". I'll have width and length dimensions posted here tonight but it is just long enough to fit under the pan floor pan (front-to-rear)on the "B". Bottom is 2x6 (18" on center) with 1/2 ply as a skin, uprights are 1 1/2" steel, through bolted on two sides and tied together with 2x6 to give the chassis something stable to sit on. Rides on 4, 4" wheels (two lockable). Floor platform was used for my parts stowage. Buck is located in Central/southern Vermont. It can be disassembled (but I'd really rather not) if absolutely, positively necessary.
Prefer local pick up. I have no way to deliver it without taking it apart. If you're in the Northeast and are contemplating a "B" build (or other small British car), this is your chance to get started right.
PM me for more info.
As promised, dimensions are 30" high, 48" wide, 55" long. Correction on the cross pieces - they're 2 x4 not 2 x 6. This is a stout buck able to hold up several times what I had on it.
