do you think I should do the bottoms and keep the tops?
Look, you're probably going to get a lot of comments and opinions here - here's mine:
The bulk of the work is digging in to the suspension be able to replace part of it. Overall, the bushings and ball joints are cheap, the labor and front end alignment is hard and expensive.
IMHO, once you dig in, replace ANYTHING suspension and steering related that is even remotely suspect. Then get it aligned with as much caster as you can get and enjoy a well handling Mopar that works well.
As a side note: I have seen quite a few beautifully restored cars that handle like s**t. People don't give enough respect to the lowly suspension parts that aren't sexy (who here has bragged about their new ball joints or bushings on their signature line? It's all engines, etc.). But suspension makes a big difference in the enjoyment of the car. Do it right and you'll be much happier down the road....
Just my $0.02
