Does anyone know of any problems associated with using JBA shorties on a 68 with a manual tranny? I read something where the equalizer bar hits the headers. Is this true? Is anyone running the setup with an original equalizer bar and not having problems?
Thanks

JBA's were installed on my car before I bought it, so I do not know the specifics of how it was done, but can report on the results. The installer used the adjustment screws that support the z bar, the connection between the engine and body, to move the z bar toward the driver's side. I'm not sure how much the bar was moved, but it looked like the bar was out of alignment by about 1 to 1.5 in. This caused an angle between the bottom of the z-bar and the socket on the throwout lever. The installer jammed the adjuster rod in which was a bad deal. After about 3000 miles the adjusting rod bent severely enough thatt I had to get the car towed. I tried to replace the adjusting rod with a repo unit of the original design and saw that it would not be a long lasting solution. I fabricated a replacement using a female tie rod with a stud and a piece of all thread. The stud of the tie rod goes into the z bar and the all thread was machined to look like the original adjusting rod. The only issue that requires any thought is how long to cut the all thread. I have some pictures at home that I could email if you're interested. The tie rod cost about $17 and the all thread cost $3 and I paid $20 for the machining. This is what the rod end looks like. I used one with 3/8" fine thread. You need a jam nut for the all thread. You also need a nut on the end of the stud, I used one of those nylon lock nuts.

Dave,
The set-up on my convertible is a little different than yours but the photograph may help; this is an eleven inch clutch bell housing, two and one-half inch pipes, and JBA 351W shorty headers.

I tried a set of JBA's on my '65 and conflict on the left was with the steering gearbox. Basically, I never got to the point where I could check interference with the z-bar. I've heard they've reconciled that problem in more recent production.
