1969 Dart 340 Auto Transmission Mount
There are 2 (technically 3, the 3rd being the spool mount crossmember) trans cross members, one (67 thru 69) with 1/2" thru bolts and one (70 till spool mounts (73 up) became the norm) with 3/8" thru bolts.
[WANTED] - 904 transmission crossmember
My understanding is one crossmember has the insulator mounting surface raised higher than the other, I don't know which is which but I do have a confirmed 67 with 1/2" bolts I can measure.
@Oldmanmopar will know.
According to rock auto there is only one insulator for 67 thru 72 A Body and they all have 2272 in their part number.
So if you got a new insulator that is taller perhaps it is for the wrong application?
