more question on project knuckle buster

[ol yellow 72]

ok me and my buddies have been working hard on ideas for my 72 rat rod called the knuckle buster
im lookin got ideas of a one of a kind rat rod shifter, keep in mind im on a tight budget. i have bounced the idea of a welded chain into a hook?
any idea on the shifter or any ideas of a cheap aftermarket or factory floor shifter to use as a starting point?
also anyone running dual stacks for the exhaust out the bed?
