50x25 can be substituted with two pieces of 25x25 welded together, they are for the seatback rails.
The 19 mm round tube is for the rear tub bends, you can skip it if you go for GRP rear end. Also, pieces of 19 mm are used in the rear uprights and the cable guides in the pedal box.
The 25 and 33 tube must be for the rollbar. 28, I believe, is for the pedal bushes, you need just 100 mm of that. 3ge do a nice set for pedal bushes -- outer, inner tubes plus oilite bearings.
33.7x2.6 are the suspension bush tubes, and 25 and 19 seamless is for the wishbones themselves.
You'll need 3 mm plates pretty soon in the build, either get a complete set from 3ge or find somewhere local that can laser the intricate parts and get some 3 mm strip and 3 mm plate for the simple parts. There are drawings of the 1, 3, 5, 10 mm plate pieces somewhere on the forum.
