Front seats

Hello, i'm new here.
I bought an early Econoline project with no front seats, the brackets are also missing...
So i'm looking for a solution. Any set in good condition available here? Or did anyone put in seats from another make/model?
Feedback is appreciated.
Greetz from Belgium.

                                -any seat will work that will fits between the dog house and door frame the tuff part is making the adjustment brackets to fit the contour of the wheel well and next to the dog house!?

I added these 2" angles to match the brackets

It's not just the width that matters.......The depth of some seats from sports cars are very long in the seat leaving little room for your legs when entering/exiting...
Also the height of the seat pad from the mounting bolts to the seat pad is usually too high on most car seats unless you like having to duck down to see out the windshield.....
I got a pair of new forklift seats from Amazon, which are freakin awesome at $85 each ( now $140 ).....
I have also noticed that there are gaming-style office chairs that have low and short seat pads that would be worth looking at in the low $100 range that I might have done if the forklift seats hadn't worked out...
