    Need to find out if any other door will fit my 1935 T,mine has the wood re-enforcement and want to swap out for steel re-enforcement…

    My doors are in great shape,but want the steel instead…

    • Stay true to the original I always say.
      Replace the wood. It will keep the integrity and the value up.

    • Have a 1938 80 D. Had to replace 1/3 of lower half of Driver and Passenger door skins. When door skin is removed then it is easy to fabricate replacement metal frame for wood frame. Unless you are skilled at metal fabrication and welding, you should stay with the wood.

    • Welcome Trent,
      Glad you have an interest in Diamond T trucks! They were the Cadillac of trucks of their time! I have a ’47 509 and joined this site to gather and share information with other enthusiasts. If there are any trucks for sale here, you’d have to look in the classifieds section. Other than that, keep an eye on the internet as they do come up for sale from time to time.
