Here's another thread that adds to the confusion,... with a member saying that CPPJEFF said,... it move the wheels in 3/4" per side,... (again COMPARED TO WHAT?)
1) Drum brakes?
2) Stock OEM Disc Brakes?
3) Other Drop spindles?

But yet,... in the same thread,... there is a quote from CPP's website:
Modular™ Drop Spindle Wheel Kits
Looking for a spindle and brake kit for your lowered truck with big tires and wheels?
We have it!
Introducing CPP's new modular 2" drop spindle and drop spindle wheel kits for 1960-87 Chevy pickups.
Our exclusive new design helps solves tire to fender interference commonly found with lowered trucks.
Our new modular spindle and bracket works with factory 1971-87 C10 brake components, or for a HIGH performance option, combine our spindle with the NEW CPP 13" Rotor Twin 52mm Piston Brake Kit.
The ALL NEW CPP Modular Spindle offers many benefits available for the first time, installs easy without modifications, works with factory ball joints and tie rod ends, lowers your truck a full 2", offers adjustable steering stops, provides 1-1/8" more fender to tire clearance, allows use with standard factory brakes and PERFORMANCE aftermarket "BIG" Brake Kits.
You can count on CPP for impressive quality, performance and price.
Drop spindles also sold separately.
Ok,... so my math skills say that 1-1/8" is only 9/16" per side.
So what is it?
And compared to what?
All I can say is these CPP Modular spindles are the
narrowest drop spindles out there for the 60-87 trucks.
But they are only an advertised 2" drop.
So back to what I always say.
Install them and then,... measure your
own truck for wheels.
There's no other "sure fire way",... than that.
