I bought a door seal kit from LMC trucks. They are installed but are very stiff. It takes a lot of force to close the doors. Do you think they will soften up or collapse enough to allow adjustment of the doors?
I left the doors shut to see if they set up different.

It takes about 2 years, but yeah, they do get easier. If you didn't re-adjust your striker after the install, you're likely trying to close it too far for the new seals.

 

ive just fiited new door seals to my 54 it is abit tight but at least i won't get any rattles.

 

Probably not. I used the same seal kit on my 48 from the same source. Even after sitting all last winter with the door closed the seal was as hard as ever when I tried shutting the door this spring. I've spoken with other 48-52 truck owners at shows and the ones who's doors seem to seal the best and shut well used something other than the stock seals. I think the rubber used in the stock seals is just too hard and what we really need is a hollow rubber seal like used on more modern vehicles...

If you find a source for something like that let me know.
