I have the same problem. I moved to St. Cloud couple years ago and can't find much. For the machine work I know there a machine shop behing the vfw in waite park off of division. For the rest you might head over to heartland 4x4 off st. germain in east st cloud. Only places I can think off.
Call Paul Brand. He does a weekly auto talk show on AM 1500 KSTP on Saturday and Sunday afternoons. I would think they would have an affiliate radio station in your area where you could catch the show. www.AM1500.com lists the affiliate stations for most of their shows.
He used to race I think and may know some other HP people scattered around the state. Quite frequently, if he doesn't know something like that, one of his listeners calls in shortly after that with info.
