CRAGAR S/S Wheels on 71-72? Bolt pattern specs?

[chevy55tool]

Anyone know the bolt pattern specs for a stock 1972 C/10 half ton (5-lug front discs/rear drums)?

Does anyone have any pics of 68-72 with Cragar S/S wheels (15"-17")???

I'm contemplating getting these 17" Cragar S/S's for my C10, but want to make sure I order the right size bolt pattern:



Also considering Cragar's "Street Lock-D" Wheels:





Haven't decided which wheels to go with... leaning towards S/S wheels.... any suggestions?

Here's the truck they'll be going on:






Thanks for any info/advice/suggestions.
