Stripped down my 68 camaro convertible after having a 350/4 speed many years and a 396/auto a few years the body needed rescued so has been a year now, and still on the metal.

Got a salvage 04 GTO-LS1/6-speed this past spring, stripped most of it and removed the dash, all wiring, cut out the floor and began retrofitting into the 68. Course the dash's are deeper and all and by measurements the GTO firewall protrudes in about 8-9 inches from stock firewall. Less cabin space and will end up with no rear floor space but the big uplift is using the massive AC/heat unit, entire dash, column,pedals, both masters and all electrics can be incorporated as the GTO most all modern options.
The wiper assembly and top cowl will be most challenging as the GTO is curved and wiper motor and arms are hideaway of course so I'll get fancy but conforming later.
Away goes the old kick panel doors and window cranks won't be visible so motors are a must.
Using the GTO floor will have to be lower as the floor to window base is 1-2 " taller, floor width is wider by about 8 inches so hacking is the fun-yea!

Trial fitting the GTO dash. upper dash to floor is about 1-2 inches taller in GTO so the floor out of the GTO will be 'sunk' a bit without sacrificing much subframe height/body.


Just checking clearance with A/C heat unit as this is the big driver to change out the dash/firewall interior. Have a complete 04 GTO car to use.


I'll cut the GTO curved portion to meet into the original cowl surface so the grill header will sit. Will blend the donor dash and cowl areas and will give me 'space' between the original firewall and deepened firewall for the cable cruise, CB/fuse block(both were mounted on the GTO pass wheel well) and ample space for the brake and clutch masters. No kick doors of course but will see how can incorporate the side vents as the GTO plumbed into upper door fronts and blasted out of doors.


More engine clearance and radiator/fan/condenser space utilizing most from the GTO(recovery tank, washer bottle). Engine/trans will sit back a few inches. Door cranks will be blocked in interior though.

 

Holy smokes! that's quite a project! Can't wait to see the finished product.

 

Hi Y2K, crazy I know wouldn't do this to an original. Lots of sheet metal rot I overlooked for many years so want to modernize it of course like all nowadays
