67 Barracuda project

Started off thinking about putting fancy 4 link systems like qa1 or street lynx in the rear and maybe Gerst suspension up front. But now I think I would like to just keep the stock suspension just with upgraded items from Hotchkis or something. I'm wanting a street strip car prbly focusing on strip a little more. I can weld but I don't have a shop to work in so ease of installation would be nice.

Car is a "built" 360 approximately 400 hp, 3 speed manual, 8 3/4 rear end with the 489 center section.

Upgrades so far: TTI ceramic coated thermal lined headers, TTI X pipe, 3" exhaust w/ super 44 flowmasters, MSD digital 6al, MSD wires, MSD Blaster 2 coil, Holley sniper EFI throttle body, Holley dual sync distributer, Holley sniper efi gas tank, Moroso electric water pump, Afco alluminum radiator w/ electric fan, stock rebuild on front suspension (pitman, idler, tie rod ends, CA bushings), Foose Legend wheels, removed front bumper

The next area I want to focus on is transmission, rear end, and suspension. Thinking on going with the tremec tko 5 speeed, and rebuilding my rear end with 4:10 gears with eaton detroit lockers. The car has subframe connectors. Suggestions on leaf springs, (inboard mounts?), sliders? panhard bar, sway bar ladderbars? Narrow the axle? Looking to get at least 275's under rear (would love 305's) and for car to hook up straight line but not be a total pig in the corners.

Some pics of car when I bought it:
