That would have been a '69 Judge powertrain, right? No Judges in '68 IIRC.Might have been. Dad was a salvage rebuilder, and IIRC we got the car as a stripper with no title (used the sheetmetal on another car that had been parked at a rock quarry during a tornado - it got gravel-blasted). Door tag showed a mfg date in '68, but it could well have been a '69. He got the T-Bird with no engine, and couldn't find another 312 to put in it, so he used what he had laying around.
Lotsa GTO's ended up in Boneyards...Lotsa Boneheads driving them, I suppose. Got mine off of a drug dealer. Didn't know that at the time, though. Got pulled over a few times and had the officer thinking I was the former owner. Even found a few hidden compartments. Guy had welded a small box under the floorpan beneath the driver's seat. Had a sliding door there. I'm lucky he didn't leave anything behind (at least I never FOUND anything). Guy I sold it to - a Jackass - drove it through a house after having it a week.
Another one of those cars I should NEVER have sold.
Did see a new Holden Monaro/GTO a few weeks ago. A travesty...overpriced and ZERO appeal.
