Metlcutr55 (Ken and Ken),
Welcome to the Bolt!

Can see that folks are already working on providing you some answers.

Judging from you post, sounds like you have an original 1 ton pick-up truck that has been modified into a "dumper" bed as some folks call them. Still a pick-up, just not quite what it started out as from the factory.
Would make a couple of suggestions to help you with your many questions.
First, make sure you ask questions in the appropriate forums. It also helps to keep questions focused on one (or an immediately related) topic as too many different questions tends to result in a hodge podge of answers. Difficult to sift through and line up the answer to the question at times.
Pictures speak volumes! Any time you can post a picture, please do so. It will help immensely.
Searching for parts and sources is very much tied directly to using the correct make/model/year info. There are tons of free on-line resource links with many original books, manuals and parts catalogs to help you in your search. If you search the various Bolt forums, there is a lot of historical knowledge ready for the reading and using to help you out.
Would also suggest you post in our
Welcome Centre. Introduce yourself and your truck to the community as there are a number of folks with trucks just like yours that are willing to help.
Also suggest you post your truck specific questions here
Tons of Fun as that forum is specifically about your size truck.
Others will chime in further here I am sure! Glad you joined us!!!
