If needed, frames can be coldest(stretched).
Some later 80s frames will accept 9speed cassettes as is.
I would think there would be a dozen(at least) bike shops in and around Denver that could confidently spread the frame. I say confident because around me there are a couple of shops which would spread a frame but I would be leery based on other things. I am sure all metro areas have that short of thing. A shop that has been around for years and deals with all types of riding(not just tri/road) would be a place I would look for.
You can spread it yourself too. Sheldon's site has step by step directions on how to make sure it is aligned once spread. I spread a frame last winter from 126 to 130- its 35 years old and still aligned great.
