Anyone have Iroc wheels on a bagged 71 or 72 truck?

[Jayschevy]

I have a bagged 71 C10 and need to get wheels for it. I love the look of the Iroc wheels but they only come in a +10 offset size. I'm not sure if these will tuck on my truck because I read somewhere that the axle's on the 71 and 72 year trucks are wider. Just wanting to see any pics or get info from anyone who has them on a bagged 71 or 72 to see if they'll fit or if any mods will need to be done to make them fit.

Thanks
