Proud new owner of this 70 suburban - and I have a few questions

[TheNasty0ne]

Well about a week ago I picked up a 70 suburban..... And I have a few questions....

First off the truck was lowered... And well I think they did a crap job... So im redoing it all....

The truck has blocks in the rear and springs in front and back but my question is can anyone tell me how many inches are the drop springs in the back judging from this photo



I bought new 3 inch drop springs formthe rear and i want to achieve that exact height... Do you think i bought the right size? I also bought all new shock relocation brackets and nitro slammer shocks... I cant wait to install this stuff

The truck rides like crap right now itsmpretty bouncy...

Also it has a 350 with 3spd tranny I assume its a 350th tranny... Is this enought to tow my other project car around??
