Torque arm bush
My IROC has a 2 piece rubber bush for the gearbox end of the torque arm .
I'm currently doing an 5.3 with T5 swap so the gearbox now sits square and not angled , I will be making a new mount for this bush but I have seen other bushes that are one piece , I would rather use one of these .
Can anyone tell me or post a link as to the correct bush I should get to fit the torque arm.
Here in New Zealand I can't just go down to the parts shop and get something for a third gen as they aren't so common . I have been getting all my parts sent from US ,
Thanks in advance

Re: Torque arm bush
Not sure which arm u have but this is for a stock arm. Very early cars had a different facing slot for some reason

Re: Torque arm bush
The 3-1111 or 3-1112 is the right one. You need to figure out which torque arm you have and get the correct bushing. the W shape on the end of the arm faces different directions with no real way to tell besides looking.

Re: Torque arm bush
If the Torque arm is factory Thirdgen part:
Torque Arm that's solid is the early style, 82-84(5?) and the "fingers" will point to the passenger side.
Torque Arm with "holes" in it is the later style. (85?) 86-92 and the "fingers" should point to the drivers side.
