Thanks for help. I removed Int., carpets, oil pad covers, factory sealers and I noticed she has a factory 4 spd manual square hole with factory stamped plates on the top and under, I'm so confusing which is one mine had the factory th400 auto. in the group 2 - "Z" OR "B" 3-spd Manual Transmission Floor Shift. There's no code "B"... The whole body shell has never been cutted off or welded around to modified it.. it's all original body panels, included floor panels.
Body tag with red marked "Z" in the group 2:
721 04C ST 67-22637 LOR22636 BODY TR 260-Z K-1 PAINT WL 2ZGS 3JF 5Y
Is that from the factory error or previous owner did swapped the body tags?? Just curious.
This is my old pic of '67 1/2 Firebird (7/27/67) w/ '74 Pontiac 400/400 on Jan 1st, '90. She had original Tyrol Blue Ext. with Std. Dark Blue Int., 326 2bbl, 4spd, 2 traction bars, 1 of 6,078 built in '67. I'm the current owner of '67 Firebird 400 coupe with original code F-400 Option, 1 of 22,636 built in '67 with rare T400. My brother & I picked her up and brought her to my new home. It's original eng. & trans. are long gone. Has factory K-Gulf Turquoise under primer, had Ivory vinyl top. Has factory RH traction bar w/ 3.08 gear, J-custom option with original Deluxe Parchment Int., has rare fold down rear seat. I'll look for a good running '67 400/400 when it's done.
