1969 Skylark Build

[HELLBILLY]

Hello all, I have been lurking around for a while try to soak up as much as i can. Now its time for the questions.

I am Starting to rebuild my first car a 1969 Skylark. I am planning on doing everything i wanted to do to this car and couldn't afford to.

I am going with a Built Buick 455 and a keisler T56.
HPI reinforcing kit and ABC's mini tub kit.

I am at a crossroads on suspension upgrades.
What should I use, Global west, DSE, speed tech, chassis works.
the choices are overwhelming. I'm trying to keep the price tag for the chassis, powertrain, fuel system and exhaust under 28k.

Any input or personal experience would be great thanks.
