I'm hoping someone can take a couple of pictures for me showing how the front bench seat rails fit into the floor of a 57 Super 88 four door sedan. The seat I have is bolted onto studs that stick up from the floor on the front just like the back rather than sliding in like the stock rails do. Whoever had the car before me installed an electric that doesn't work so I want to convert back to a standard manual bench seat. I purchased some original seat adjusting rails but they slide in rather than bolt on in the front. Am I missing some brackets that the seat rails slide into? If so, do these brackets bolt to the floor and then the seat rails slide into them. If I could see a picture of a stock set up, I can see if the previous owner Mickey Moused something or I'm just missing some parts. Thanks in advance for any help. Dan

 

There are two bolts 3 3/16" apart hold a 'U' shaped strap that the seat rail slips into. No pic. Not the safest of ideas by to-days standard.

 

Thank you! I see the two bolts so that makes sense. I think I'll fabricate something a little stronger though. Thanks again for the quick answer!

 

I think I used these brackets sold new for tri-five Chevy easily found on that auction site

 

Thanks 59-59-59! I ordered the brackets you suggested and they're going to work. Even the holes for the bolts fit perfectly! Thanks again. Dan
