madkaw Posted August 9, 2010 Share Posted August 9, 2010 Looking for ideas for a tranny mount bracket for a bwt-5 that has been installed in a 71 that originally had a automatic trans. My chassis is set-up for the mount bracket that bolts vertically into the chassis. Right now I have reworked the original rubber mount that seats on the bracket to adjust for the offset. I also oblonged the mounting holes on the bracket. The problem that I might have incurred is damaging the integrity of the rubber mount by welding and cutting on it. I tried to be careful and took my time welding and keeping the heat from building around the rubber, but the mount seems to be too loose. So is there a better alternative? I have searched and searched, but most applications I have seen were for the horizontal type mount. I saw one that utilized a urethane type mount that would be great, but again the bracket was for a horizontal mount. I think the offset needs to be greater for us guys that started out with an automatic. The pictures show what i have now. To remedy the offset I moved the ears of the mount so that the mount would center the bracket. I also had to notch the mount so it would slide foward on the tranny to center.

Nigel Posted August 9, 2010 Share Posted August 9, 2010 Why not do something similar to what I did for my 240SX transmission swap, but with the right offset for the BW box... I made a simple jig out of an aluminum bar. You could do something just as easy for your style of mount. For the complete 240SX transmission swap guide, click this picture...

madkaw Posted August 9, 2010 Author Share Posted August 9, 2010 Nigel, thanks for the response, but that involves using the horizontal mount and mine is the vertical. It might come down to fabbing brackets that I hang the horizontal bracket from my vertical based chassis so I can use this type mount, but I was hoping for less fabbing requirements. Nice work though! Quote Link to comment Share on other sites More sharing options...
MAG58 Posted August 9, 2010 Share Posted August 9, 2010 I have the vertical mount like you. I just took a pair of angle iron brackets  and drilled some holes so that they extend backward a little bit and I then bolted the bracket to that. I'm sure there are nicer or better ways of doing it, but my car has seen about a year of DD service with that trans and no issues. Quote Link to comment Share on other sites More sharing options...
madkaw Posted August 9, 2010 Author Share Posted August 9, 2010 yes bob that might be the easiest solution since I do have one of the horizontal cradle types somewhere. I guess I will go back to the fab shop and set it up for a urethane mount and make the angle brackets to suspend from the verticle mount so I can use the other type mount.

madkaw Posted August 9, 2010 Author Share Posted August 9, 2010 Bob, I reread your post and I could just move back the bracket i have now guess. At this point I will have to get another bushing since I altered mine. Anyone see a problem(since I will be fabbing anyway) to use a urethane type bushing(similiar to the type on a RT mount) or will this be to stiff compared to the stock and harm the motor mounts. I believe the bracket i have now(horizontal) has good rubber bushings to isolate noise. Somewhere on this site someone has done this, but can't find the tread to see how's it's working for him.
