G BAR type Kits available ?,,

[usa-69z]

i have a 69 camaro which im about to mini tub using dse gear,, I have a couple of questions if anyone can help..?
I have a ricks vapor worx tank in there now to suit my injection setup.. can i keep this with the DSE minitub ? im thinking about a G bar setup instead of rear leaf springs.. What other brands/manufacturers make these g bar suspensions? ive only seen chris alstons but no others.. I want something with not much in the way of cutting etc as my skills are limited..I thought by eliminating the rear leafs i may be able to keep my fuel tank as it is ?

thanx , Gav
