Mowjo, I am currently building a 67 Firebird. The following changes were made from stock; 1. pulled the front subframe and rebuilt it with polyeurethane bushings, reset the upper control arm mounts (Guldstrand Mod). installed a ws-6 steering box from a 78 T/A, available at parts stores. Guldstrand shorter than stock front coils. I am using 17" wheels due to availability of 17" performance rubber. 16" is not as readily available in the sizes I chose to use. 17" wheels made it possible to use 13" front rotors from a c4 corvette along with ls1 camaro front calipers. Speedtech makes the brackets needed. For the rear I chose multileaf springs with poly bushings for a 69 firebird, mainly since they were easy for me to get. Alot better than the monoleaf anyway. I am using a 9 inch ford differential from a 65 T-bird that was given to me when the T-bird was scrapped. luckily it was a bolt in job and little fabrication was needed. I am using 17x8" in front and 17x9" in the rear for wheels, shocks will be either Koni or something similar. I plan on subframe connectors in the future. Tires are 255/45r17 in front and 275/40r17 in rear. I did have to fab up some offset spring shackles however to mount the diff. I did this with the shock spacers from 80's Chevy Caprice. They are big steel spacers and they fit perfectly to move my springs inboard 1/2 inch per side. I aint no know it all by any means but so far this has worked good.
