Sorry GKMOPAR.... I went to get a pic for you and found out I haven't installed the lock linkage.
I thought no problem I'll install it real quick and get a pic.
Looking now I see that I don't have a place to mount the transmission bracket. I don't know if it's the same situation on your car. The linkage is from the car originally (I found it in a bag I marked YEARS ago)
The Tranny is from my 74 Cuda and is not original to that car. I'm wondering if 70 only had a mounting location for the bracket. The non original transmission that came in the Challenger is long gone so I can't even check it. Maybe someone will chime in.
Also .. I might be wrong but it seems like my headers will be right in the middle of the locking linkage.
