Good day Davemila. you might find your answers if you use the search box at the top of the page. Also, maybe a little intro about yourself and your scrapping history to let the wonderful people on the forum know who and what your all about. You might want to start by reading the forum rules here https://www.scrapmetalforum.com/introduce-yourself/ and go from there.

There is a whole bunch of information already on the forum, all you got to do is find it. This is not meant as being arrogant at all, just some friendly advise to help your endeavors in the scrapping world.

Happy scrapping
