Tubbed my rear fenders in on my k5 and only have 41" between them now. Looking for a low sitting (basically on the floor) seat that is 40" wide. Any ideas?

I assume you want a stock seat? I had a PRP rear bench made. Mine is fullsize but they make them to length. Other than that you could try like a Sami or something else small. Or you could run a pair of buckets in there as well.

Rear jeep seat?

looking for a junkyard seat that is 40" wide. How wide is your jeep seat?

I think it's like 35" wide. Not positive though.

yeah would like to find something that fits a bit better. might just have to go out measuring but would rther have an idea of what to start looking for.

I would look at rear seats for minivans
