I asked some similar questions over on the Team Camaro site regarding Z ed specific Pitman & Idler numbers - you may want to go to the attached link below and see what many other Z 2/8 owners over there responded with...
The thread was about Z 2/8 ownership and I guess I got them off topic about 8 or 9 pages into the thread with Piman questions...

"68
The 3908391 long pitman arm was used in 68 Z28's. Other 68 Camaros used the 3935075, 5.25" long, pitman arm (both manual and power steering). The idler arm for 68 was 3917581, 5.25" long."

Chick did this get figured out, My 68 Manual Z also has the 075 & from the .net thread quoted 'others' have reported the same.

Hi Jim, sorry for late reply.... After confirming other Z/28's had the same 075 as mine I never worried or researched further. It seems both 3908391 & 3935075 were used but we know a lot of NOR cars had the 075 for whatever.
Our 68Z trim tag build date 01B
Plant-NOR
Steering Arm 3935075 A
Steering Box manual 3567 or 12/22/67

Chick has a short pitman with a long idler.
never2many has a long pitman and a short idler.
Missing the logic so far. :)

We need more data - on all 3 components.

Steering arm - 391
Do you mean pitman, idler, or steering arm?? I thought steering arm, but now I think you meant pitman.

Post by: cook_dw on March 23, 2023, 03:19:11 AM: Yeah my fault. I meant pitman.
Title: Re: 1968 z/28 pitman arm
Post by: KurtS on March 23, 2023, 05:59:42 PM: Realizing we had a terminology problem.
Pitman - attached to steering box
Idler - attached to subframe, mirrors the pitman
Steering arms - connected to the outer tie rod and attached to the hub assembly, we haven't posted data on them, but there are several versions.
