Hot Rods Seat Belt Length

Anyone know what seat belt length I would need for a 1951 Chevy Styleline coupe? 60", 74", or 90" Regular sized guy with seat all the way back. Seats are at upholstery and I need to order the belts. Going with single none retractable air craft style buckles. Thanks

 

Most front seat belts are normally 72 inches.

Thanks

 

I ordered the belts for my deuce 5 window from Julianos and apparently they have 2 lengths and I didn't pay any attention and after installation they were to short. I reordered the longer belts and they are fine. Of course now I have this pair of short belts to sell on my estate sale!
