you start with a linking the front and it up with an all out truggy.
say $300 in flex joints
ballistic charges $16 a foot for the link material although you can find it much cheaper.(2"x.25" wall)used 9 feet in my 3 links plus another 3 feet in the panhard(different material though)
plus bracket making your own or buying.
plus tube adapters.
ballisticfab.com will be your best friend and your wallets worst enemy
