Stock 30/31 RPU Seat

[Cabbie.a12]

Hello All,

What are the stock dimensions for the bottom, and back spring for a 31 RPU? I came across a new set that was at an estate sale where the guy restored A's, and T's.

One spring is 42.5" wide at the back width, and narrower at the front. It is 18" front to back. The pics with the cardboard are what I think is the back. Thank you for the help, as I can find any measurement information.

In 31 the bottom spring changed; I think it may have been when the indented fire wall was phased in. The later spring is shorter front to back.

I have heard that also, but nobody shares the actual dimensions. At this point, I wouldn't care if it was an early 30, or a late 31. I just want to know what I'm looking for.

If the cushion is for a truck it will have two loops,or tongues hanging down in the front.Those snap down behind the front of the seat riser to hold the seat from sliding forward.
