Headrests and diamondplate
I got the headrests from another site member. I think the its the mid 90s on Rodeos and they look the same as what I had in my 94 Amigo. I'd put out a "wanted" or hit up a yard. Can't be a huge demand for Isuzu headrests (other than this forum) Anyway, they about double your visibility out the back, which is why I bought them.
Not sure how much metal would be, have to check around on that. I'm sure someone has extra diamondplate, however not sure if you have an air-nibbler or something to cut it with.
