Re: In need of a few measurements
My plan once I've refurbished all the components:
Reassemble the top upside down, without springs, and measure the relationship between the frame and the top, then measure the van towards the rear and see where it lands.
I'm guessing I'll find that the frame is meant to bolt to the roof crossmember at the rear of the cab.
The one I salvaged is basically two rails that run front to back and a rear galvanized piece that goes between the rails. The front was held in place by the van's structure. The hole was 46.5"x 107" which may be the same as the dimensions posted here, depending on where it was measured.
