Lowering help 70 SWB

[swokcguy]

I have a 70 that was cut down to a SWB that looks like it was done right (so far). However, someone did a homemade lowering on it all around. Looks like they did the axle flip conversion for the rear and just heated the front springs to lower the front. This is not acceptable to me at all because the truck does not ride worth a damn at all. The rear does have leaf springs, whenever I go through a dip or hit a good bump, the frame and the axle housing meets with a vengeance. My immediate thought was to throw air shocks on it before I really cause some damage, but wanted to check some of your opinions.

It looks like everyone is going with the 5/7 drop, but I really don't want to go that low. I am going to stick with 15' ralley wheels for a while (maybe forever). The 2/4 drop is more what I'm looking for, this is a daily driver which is mostly highway now.

Any suggestions would be appreciated. Here is a current pic of it, I like the stance it has now, but wouldn't mind going a little higher at all just not stock height.
