Helms manual

This is my first time posting so i’m really sorry if its in the wrong section. Anyways i have been lookin for like the past week for a Helms repair manual for my 90 ls teg. I searched in the forums for like an hour a day and found nothing useful. I also went to the helms website and they said they don’t sell them and the member who had the entire thing on his webpage no longer has the site open. So any help on where i could get it would be greatly appreciated.
