Should I be assembling my rear end myself?

[steve671]

So I just got my rear end components for my 69 Camaro. I got the Chassisworks Fab 9", S-series 3rd member with 4.10's already installed, Strange axles, and Willwood 13" discs with parking brake. I have years of experience working on various parts of cars in a hobby capacity, but have never touched the inside of a rear end. Is this something you would take on and be able to figure it out along the way, or should I pay a rear end shop to assemble it? Would like to save the money if possible. There are no instructions though
Thanks,
