belt squeal

hey fellow yoter owners! I have a question about an 88 EFI it was given to me by my grandmother who had it since it was new and its been in her yard for 15 years. There was some preety bad rust but I patched it up with some bondo and its good as new. But now after driving it a while ive noticed a new problem.

When I Rev it up in N 1st or 2nd a loud obnoxious squealing comes from the engine bay, could the be the belts or comething worse?

You mentioned squeal in first or second gear. Does it do it in nuetral, or with the clutch pushed in? If so, it's probably just needing new belts. My 22RE in my king cab 4x4 sounds like crap for a few moments, especially when just cranked-up, it's just too cold/windy/rainy to mess with right now! I'll turn up the XM a little bit louder!
