[Half-Inch Stud]

67-69 Bird Front Disc Spindles..."Convert Drum Spindles to Disc; all you need to do is mill about 1/4" off of one Threaded Boss"
Then supply front disc caliper brackets for a complete conversion kit. I do not know if there is an availability issue with the Calipers these days..got two from Pepp Boys in 1992.

69 Bird Manual Steering pitman Arms. Curved would be nice, so Long-Branch manifolds can be used during full right-turning radius.

67-72 GTO and 67-69 Bird Replacement axles:
7/16 studs on Standard pattern with half-inch studs on the 5" pattern. May as well make these axles capable of street/strip.

67-68, & 69 Bird and GTO In-Dash stereos that accomodate the dash centerbar..may as well include 1/8 inch stereo input for remote CD player, Seek/Scan, Must be lighter than GM stereo [img]/infopop/emoticons/icon_smile.gif[/img]

69 Dual bailing wire Brake Master Cylinders made in Aluminum.

SFI approved Harmonic Balancers...without the high price, like under $100.

67-69Bird Headers with 1 7/8 or 2" primaries.
some minor tube bend improvements to boot, like skipping the equal-length foolishness.
