Quote from: 06GT on January 23, 2018, 02:26:03 AMThe short answer is about half of it is the same. The other half is different. The alt adjusting bracket is different and most like the driver side smog tube. The pulleys will all be different. You can also use most of the hoses. The 66 smog parts are completely different then 68-70 CJ stuff but the 66 smog parts will fit on the CJ engine the same way as on a 67 PI.
Just bought a 1966 Tbird with a 390. It's got the air pump all the hoses brackets heads etc. Is it usable/same as on GT500? I'm going to end up with my 428CJ in it so I won't need the emissions stuff.
