For helping keep this great

on the Internet for over 30 years! and not clogged down with Ads! Again, thanks! | | | | Joined: Mar 2009 Posts: 58 New Guy | | New Guy Joined: Mar 2009 Posts: 58 | I have a 54 bed installed along with my 54 cab on a 53 frame. Yes, the hump over the rear axle has been modified (lowered and boxed). Everything fits as you can see on my truck pictures. I would like to try installing the cross sills in the original locations if possible. Would anyone with an original 54 bed be willing to give me the measurements, front to rear, of placement? How many inches to the center of the first cross sill, from the front to the center of the second, etc. I don't have any trucks around me to look at.

I would mock up the rear cross sill and measure locations for the other bolted-on sills from the holes in the strips.
Current fleet (subject to change w/o notice) \'49 GMC 3/4-Ton , 60 Austin Healey Frog-eye Sprite (some assembly required), 2011 Dodge Avenger, 2015 Jeep Cherokee. No, they don't all run. My other ride is a (B737)no, (B767)no, A320.... Update... was Embraer E190, now Boeing B787. Knowledge is a wonderful thing, but ignorance means you don't know you can't do something.

I'm in the Island Center area on Bainbridge Island so its no more than 50 or so miles from anywhere that can be called Port Townsend.

But thanks though. I'm 9 hours south of the Arizona border. Restoring this in my garage in Alamos, Sonora.

I have the bed strips here so I should be able to locate the positions with your info. Thanks again for taking the time to do this.
