70 Pontiac Tempest/Vette wheels?

[bart007]

I am used to doing things by trial and error, but in this case I would like to figure through the hard stuff w/out wasting a bunch of money. I am planning on a set of Late model Vette wheels for my Pontiac Tempest post car. The rears are 19X10 and the frts are 18x8.5. Two questions for those in the know, what will I need to do to my car to allow them to work? What would be a good tire size combo? I see several Chevelles sporting these type of wheels so I know its doable, but have'nt run accross any threads expalining the process.
Thanks in advance, Art
