socorob Posted August 12, 2013 Share Posted August 12, 2013 Has anyone used the transmission mount with bad dog frame rails? If so, did it fit between the rails or did it need to be cut and shortened? Quote Link to comment Share on other sites More sharing options...
ktm Posted August 12, 2013 Share Posted August 12, 2013 (edited) I had no problem installing the JCI mount on my car with Bad Dog frame rails. It is a tight fit though. Not interference fit tight, but there is not a lot of room (if any) for play. Edited August 12, 2013 by ktm Quote Link to comment Share on other sites More sharing options...
socorob Posted August 12, 2013 Author Share Posted August 12, 2013 Thanks. Do you have a 280? On that note, does anyone have one not installed yet for a 280z that they could measure the length of? Quote Link to comment Share on other sites More sharing options...
ktm Posted August 13, 2013 Share Posted August 13, 2013 No, I have a 240z. Quote Link to comment Share on other sites More sharing options...
nick-james Posted September 13, 2013 Share Posted September 13, 2013 I had to shorten the JCI tranny mount by about a 1/4 inch. It "looks" like it might bend but that metal is THICK and is very rigid. I just cut the thing in two and rewelded (bevel cut). You can take the extra 1/4 inch out of one or the other side, it didn't seem to matter because there is a little "slop" in the tranny mount and it will still be pretty much centered.

socorob Posted September 13, 2013 Author Share Posted September 13, 2013 What trans mount did you use? Quote Link to comment Share on other sites More sharing options...
Phantom Posted September 18, 2013 Share Posted September 18, 2013 Keep in mind that all these cars are really old and over the years specific dimensions have probably changed a bit due to years of driving stress. Even if a car has never been in an accident it's possible a 1/8" interference fit on one could be 1/4" loose on another. Just too much happens over the years.

nick-james Posted September 24, 2013 Share Posted September 24, 2013 What trans mount did you use? The stock t56 mount. It would be hard for me to believe that the distance between the frame rails has changed that much because of driving fatigue. One possible explaination might be that people have jacked up the cars on the rails and dented or bent the rail. Mine were sorta bent before I added the bullydog rails.
