Car came with st300 and shifter. Car now has th350, and will be going back to stock shifter that will be converted to a 3 speed with new detent plate.

The parts manual diagram shows 2 different trans levers depending on either AT or HD, with 2 different pn's.

Does anyone know the difference between the st300 and th400 trans shift levers? Is there maybe a different length? Different angle when mounted on the shaft?

I had to share a little FYI for someone else who might encounter this. Definitely not a dig against Doug's headers. They make a fantastic product and would absolutely purchase again.

I'm working on one of my two firebird projects. Installing a pair of 1 7/8" Doug's headers. The motor is an IA2 block with screw in freeze plugs. I also further added some complications by replacing all the front steering components to include the passenger side idler arm.

There are a lot of opportunities for stacking tolerances especially with these old uni-body cars but the motor mounts are new poly type, the body bushings are all solid aluminum and the chassis was verified for square and all the moving front suspension pieces have been replaced. All in all a pretty decent starting point.

Driver side header went in perfectly, nice and snug fits like a glove. An honest 15 minute job. Passenger side, not so much.

First fitment issue I ran into was one of the down tube were making contact with the passenger side steering idler arm ball-joint. I thought to put the old super-comp header in and they too have the same issue. I went digging through my old pile of junk and found the old idler arm. The new idler ball joint is just a little over 1/8" larger in diameter. A little torch work and a dimple, problem solved.

One more last final test fitment and problem number two surfaced. Upon final tightening of the header bolts, there seemed to be a very slight binding. Using a plastic tie wrap to feel around up in the blind areas, came to realize that the rear screw in freeze plug also presents a very slight interference as well. I'm thinking the screw in plugs weren't worth it and should have just stuck to the press in type.

Just a little public service announcement. I'm sure every car has it's quirks but if anyone is planning to put the 1 7/8" Doug's headers into a first gen with an IA2 block with screw in freeze plugs and if you've replaced the passenger side idler arm, may I suggest a good stretching session before starting ;) ]]> 67-69 Firebird TECH punkin https://forums.maxperformanceinc.com/forums/showthread.php?t=886127 Ignition rack and sector gear https://forums.maxperformanceinc.com/forums/showthread.php?t=886117&goto=newpost Thu, 02 Jul 2026 18:34:34 GMT Dear Firebird enthusiasts I recently purchased a 1969 Firebird 350 V8 manual transmission, and it is really fun.

Dear Firebird enthusiasts

I recently purchased a 1969 Firebird 350 V8 manual transmission, and it is really fun. Unfortunately, the ignition lock stopped working, and I proceeded to change it. I have removed the steering wheel, the turn signal handler, the lock plate and loosened the turn signal parts. I have removed the old ignition cylinder, but because it was freely rotating (and my ignorance) it was probably removed not in the correct position. I have then inserted the new ignition cylinder, but it seems to enter in the run position and it will not go to the lock position and the key is not removable when inserted. The steering wheel lock pin will not fully extend when the ignition key is turned maximum towards the lock position. I have removed again the new cylinder and suspect there is a misalignment in the rack and sector gear. What do I do?

Attached are pictures showing the position of the sector gear, the oval part is position towards two o'clock position and it seems to me that it should be more like twelve o'clock position. The other picture shows that the locking pin will not extend fully.

It is a non-tilt Saginaw steering column.

All help appreciated!

Thank you
