Fordor front seat base

[Brewkett]

Hi everyone,
On my journey with my new to me 1930 Fordor 160A Murray sedan.
I was working on moving the seat back to accommodate my 6'3" body and I broke the lower wooden seat frame. (I believe the frame was always cracked and with me messing with it I did it in) Looking for a Replacement for my car. I have 4 bolts on each slide holding the base to the slides. I see lowers but they look like they are for the new 6 bolt sliders. What options do I have.
