Suggestions for making my F53 a little easier to drive

It's apples and oranges, but I recently had the suspension components all replaced on my 67 Corvette. It steered like **** when I got it back-------all over the road. This was after the shop that replaced the suspension parts had it aligned. The shop that aligned it, used standard 67 alignment specs. Those were set up for bias tires back in the day. It now has (and has had) radial tires. I took it to another shop that increased the caster as is normal for cars with radial tires. The car now steers nicely.
