How much wider is a '90 Van G20 axle compared to a C10 axle?!?

Hi guys,

I've been looking to find a 3.42 rear axle for my '86 C10 2wd which has a 2.73 right now.

Well, I finally found one, but it's a G20 Van unit 3.42 posi.
I read somewhere that G20 axles are wider, but I don't know HOW MUCH WIDER overall.
I do know that I need to modify the spring perches.
Just need to know the difference in overall length.

Thanx

erik
