Title: Rear Transmission Seal
Post by: Texascobra on December 16, 2023, 03:01:36 PM
Is this the correct assembly line rear transmission seal for a Jan 67 GT500??

don't believe that ford used that brand on the assy. line. correct one will have ford engineering number on it. others will chime in with more info later.

I ask because a prior post and NPD suggest this as correct for the big input and big output top loaders.

may be 'correct' shape but assy. line never used that brand.

Yes the assemblyline seal you picture is a very close style to the one used for a 67 GT500 big input and big output top loader. As a further note the after market seal will most likely work where as the recent repro assemblyline version commonly leaked.

I thought the seals that Chris Brown made had the Victor 49720 stamping on them and he copied them from original assembly line seals.  I have one here.

There have been many reports of the ones Chris brown made that leaked.

Yes...I would agree with the comment about leaking.  I heard that. 
But as far as the Victor stamp I am pretty sure that was on the original seals.  I have one other original here but its still installed in the bare tailshaft I have here.  Dont think you can see the back side of the seal with a scope.
