What box was actually used in the AAR and the T/A in trans am series race power or manual can not find any info just curious thanks
The actual race car thanksAre you asking about the race cars or the production cars? The race cars used a manual box (at least the ones I have pictures of did).
I was just going to write a post about this. My T/A has a standard steering box, but whoever put the front end on added a fast ratio pitman arm. It steers WAY too quick. I want to put a standard pitman arm on the car to determine if this will reduce the speed of the steering. My alignment is bad as well...car wanders all over! I was unsure about whether the idler arm needed to be replaced as well. Sounds like if it is the stock idler, it will work with the stock pitman arm. Is the classic industries part #2835880 the correct piece? Is there a better part I should be using?The factory-backed TransAm race cars only used manual steering.
The street TransAm cars had three options: manual, regular ps, or else the preferred optional T/A Fast Ratio ps (marked TA on the box)... and that option had a longer "Fast Ratio" Pitman arm (also marked "Fast Ratio"). The idler arms we all the same. Later, into the 71 model year, as you could still get the optional FAST RATIO ps on 340 Cudas and 340 Challengers, it became known that the idler arm was too short causing un-equal turning radius left-right. The corrected idler arm that matches the longer FAST RATIO Pitman arm is the same from a 70-71 big C-Body car... that is what should have been factory installed with all the optional T/A FAST RATIO ps boxes.
NOTE: No company -- Firm Feel, Hotchkis, PST or anyone else... ever "created" or designed the corrected longer idler arm to match the longer FAST RATIO Pitman arm. It always has been and will be the factory 70-71 C-body idler arm. And, this was exposed many long years ago in-print via the SIAC news letter (for T/As and AARs).. to use the C-Body longer idler arm. Furthermore, I had personal discussion with Chrysler/Mopar staff about the matter to confirm that they were aware about it.... all the way back into the early 70s.
VillaT/A -- the idler arm number you gave, per Classic's web-site, is simply the standard length idler arm (not the longer C-body/fast ratio idler arm).I was just going to write a post about this.

Sounds more like an alignment problem.... also, extra wide tires (50-40-35-30 series) typically grab the crowns of the pavement and then introduce darting. The Toe-adjustment is critical, as well.By fast, I mean that minor movements produce drastic darting of the car. It is disconcerting at higher speeds. Without two hands on the wheel, it will invariably pull, especially when there are ruts or bumps-and require constant correction in the tracking of the car. I discussed in my own previous post. I don’t mean to hijack this one. My steering box is stamped 2267262. My current pitman arm is stamped 10031-103. I also bought with overresized tires. Just hoping to avoid a full steering box rebuild. Maybe I need to look into the shimming suggestions as well. Alignment is a must also.
