lcfman,
From lots of reading in the forums, the vast majority of folks have indicated that "Steele Rubber Products" are usually the best and most accurate for most our of trucks. AD era door products are still a contested subject, but that doesn't apply in your case.

Here is their link to the
Task Force Door Seals.
Their page provide a cross section view with measurements to help you confirm there product matches your original TF seals.
The Metro Soft Seal page
for your application doesn't give a cross section view or measurement of the thickness. The picture does appear to be thicker than the Steele product, so could be there is a product issue???
Hope this is helpful???
