does anyone have a drawing or a jig plan of the top and bottom wishbones that are made useing a pipe bender.like the mk ones allso does the tube have to be seameless because i cant source any

Yes, the tube should be seemless no matter what type you're making. If it's any consolation it took quite a bit of searching to find the CDS for mine, it's pretty spendy too (£15 for 3/4" 16swg and about £30+ for 1" 12swg IIRC). If you're in the somerset area I can tell you where you can get it.

Oh, just noticed your location, so steel stock holders in my area's not going to do a lot of good for you.
