Drop Spindles Question

[Darthbaker]

Ok so I need to order a set of spindles for my C10, but I've noticed a few things.

It appears there are two different spindles that McGaughy's makes. I'm going to get the 2.5 inch drop but there's a set for 67-70 and there's a set for 71-72.

Is there really any difference? I need to know because my truck was titled as a 1970, but according to the VIN it's an Early model 71.....

Advice? (besides bagging it)

Thank you
SB

balljoints and tie rodas are different.
Is it disc or drum brake now?
Drum would require the 63-70 spindles.
If it's disc,... it could be 71-72 or 73-87.
Pics would help alot.
