Cpp modular drop spindles and wheel backspacing

['68 Newtricks]

Having spent thousands of dollars with CPP, I'd won't buy or even trust what they say again. So much BS and back tracking. Descriptions say one thing, dude on the phone says another thing and calls the description out for being wrong. WTF

Here is my 2.5 modular spindle + 2 spring running 275/40/20 mounted on 20x8.5" rims all the way around. I will try very hard to get what my backspacing is in the next couple days. Personally, I wish it was another 3/4" more on either side. Please please, someone message me if I haven't by Sunday.
