I have a 1988 hi ace van. The sliding door has seen better days but was working fine until my 35kg staffyxridgeback tried to jump out while still tied to an anchor point in back of the van. She pushed the door back past it’s “ comfort zone” and I could only get it closed properly by removed the bottom roller/bracket. Can anyone give me some instructions on how to put it back on so it will work properly. I’m a fair to middling mechanic but my experience is mostly with motorcycles and kombi vans. Any help would be greatly appreciated.cheers - doc 👍
