Hi guys,

Question, going to replace the transmission mounts on my 63 convertible. I can see the nuts for THREE of the four bolts, but can't see how to get at the one on the drivers side of the car. How do you get a wrench..or a hand or even a finger on the one in front nut???

Some use dist wrench and some (me included) modified an open end wrench. A pain no matter what tool you are using.

If you have a good way to support it you can remove the crossmember mounting bolts on the left side and slightly lower the left side to gain a little more space if you have to. I generally do not bother and simply cut that one bolt out from the bottom. Fiddling the new bolt, nut, and lock washer in place is very annoying but can be done.

Ok I spent a good amount of time yesterday, trying to figure out how to get at that nut!! From what I see there is no access. I've read about the bent wrench..I see no way to snake it in there. Is it possible the convertible body is different??

I was able to get the bolt out but the nut didn't stay in place and has disappeared in there somewhere.

Help!?

Thanks!

The clearances in that spot are the same convertible or not. It is very tight. Wrench heated and bent near 90 degrees right near the end can work. The last one I did I lowered the crossmember a bit but that was easy to do at that point since the powertrain was not in the car. You can lower the crossmember a little even with the powertrain in place. Vehicle must be up and supported on lift or jackstands and a suitable jack must be under the suspension crossmember on the left side to hold it up when the bolts holding it to the car are removed. You may need to loosen the bolts on the right for it to move better. This provides perhaps another 1/2" of clearance. The powertrain I assume is already loose and lowered in the front to clear the mount. Removing the trans mounting bracket from the trans should have already been performed as well for more access. You could I suppose cut a section of the rear body steel away from the inside under the seat to provide access, but, I have always found a way to do this without cutting the floor up.

I take a crowsfoot wrench and set it on top of the bolt and then start wrenching from below. It will catch on the frame and stop the bolt from spinning allowing ya to take the nut off.... Its worked for me a few times.

Search will sometimes help. Thanks. I could not figure how to get that hidden bolt at the transmission mount on a '63. My first thought was a bent wrench, but decided to go to search first, typed in "transmission mount" (maybe I was missing something). Someone suggested a crows foot, this did not work for me. Someone suggested lowering the suspension to gain access, sounds like a lot of work and could open up a can of worms for one pesky bolt. So I bent a box wrench, first attempt: bend was to close to the box, second attempt: 3/4" bend from the center of the box, about a 75 degree bend. I was then able to get the box onto the bolt head, but because of angles of steel the the box kept slipping off when applying pressure to a ratchet on the nut below. finally applied vice-grips to the to the end of the bent wrench and applied a lot of pressure to keep the box on the bolt head, my wife then operated the 1/2"drive ratchet. The nut come off very slowly due to rust.

Thank For 'Search"
Steve D.
