Dan B., WELCOME BACK!
The "Cub Cadet Parts Lookup", see link at the top of the page is a great resource for exploded views and parts listings. Should help you sort out what bolts go where and in general how stuff goes together. Also be sure to check out the "Manuals" section of the forum. There are Service Manuals for both the 123 (1x2-3 Series) and 125 (1x4-5 Series) as well as for hte other series and various attachments and stuff.
