77 GMC Steering Gear Box and Suspension

[Rnd]

I have a '77 GMC 3+3 two wheel drive 3/4 ton.

It drives really loose on the highway. All the bushings and steering linkage are in good shape, it's just the way they built them in the 70's.

I was wondering if anybody has tried to change the steering gear box out for a closer ratio box?? ie. this box is 3 & 3/4 turns from lock to lock. In the eighties they had some that were 2 & 1/2 lock to lock.

Also this truck didn't come with a front sway bar. Has anybody added one? Did it help with the body roll?

I guess I'm trying to get a firmer/tighter feel when on the highway.

Any suggestions??

Thank you,
