The only bad thing about a ladder bar setup is if it is right, it works great, if it is installed wrong not much you can do about it, except cut brackets off and start again. Plus if you keep the car and keep improving it, what happens when you overpower the suspension and lack of adjustment keeps you from tuning it? For just a little more time and money a 4-link will give you adjustment and maybe even make the car worth more when it is time to sell.
I like to use a suspension program like Performance Trends 4-link calculator, it also does ladder bar setups. plug in the numbers and see where those brackets need to be welded.
