How much drop?

[James the III]

Hello, Mates.

I have a 71 long bed and I plan on lowering it some..

It has a 2 piece drive shaft..
I have 2" drop spindles to put on it..
How much drop can I add with springs in the front without messing up the alignment , I.E. run out of adjustment and cause it to kill tires fast..

Would 3" drop springs be ok..? or should I stay with 2" instead ?

The rear, how much is to much, here, without needing to notch the frame?
and still have it not on the bump stops or always bottoming out on them..

I may be open to notching the frame, as I'd like it to be level, no rake..

Also is there shims to adjust the pinion angle after you lower these..?
or is this a DIY item?

Thanks for any help on this..
