It could be a 1bbl car, but I doubt it. The Sprint is the only OHC 6 car to get the dual traction bars due to the manual transmission optioned on a 4bbl OHC 6. (3.55 rear gear std) They would have went to a lot of trouble to add it during the restoration. The floor brace where it is attached is not reproduced and it part of the floor pan.

According to this dealer order sheet - from another Sprint Bird
The 4spd floor shift was not available with 6cyl 1bbl

We know it's a 6cyl by VIN
And 4spd by 2L on trim tag
Dual traction bars

Does this defacto prove it to be Sprint ?
Or is the order sheet wrong ?
Appears the only manual with 6cyl 1 bbl is 3 on the tree.

I also can't find anything on internet about the 4H code on trim tag.
Have been looking at a lot of 67 Bird trim tags and not found another with it either.
Some of those were Sprint Birds as well.

Thinking it's a Fisher mod to the rear half of body
Maybe rear speaker or rear defog

Where would a rear defog switch be on a 67 Bird ?
