| | THANKS!
For helping keep this great
old truck web site
on the Internet for over 30 years! and not clogged down with Ads! Again, thanks! | | | | Joined: Aug 2014 Posts: 11 New Guy | | New Guy Joined: Aug 2014 Posts: 11 | So, I am putting a 47 cab on a s10 frame. I came to realise that the 47 has one cab mount in the center on the rear. My question is should i just utilise that or, weld plate to the floor in the corners and build a new cab mount all together for the rear.
The overall plan for this truck is to be a solid street truck that may see occasional strip time. Power plant will be mild 355 th400.

The original cab mounts were meant to allow the cab to move around, and you don't want that. | | | | | Joined: Aug 2014 Posts: 11 New Guy | | New Guy Joined: Aug 2014 Posts: 11 | Either way I go, they would be a solid mount with a piece of rubber for anti squeak. There would be no movement as am not using any of the stock mounts other then the location.... | | | | | Joined: Jun 2009 Posts: 1,596 'Bolter | | 'Bolter Joined: Jun 2009 Posts: 1,596 | Yes but having one center mount will allow for more cab movement. | | | | | Joined: Aug 2014 Posts: 11 New Guy | | New Guy Joined: Aug 2014 Posts: 11 | When you say movement, you mean not so much side to side movement but more of it wanting to pivot on that mount.... more like flexing on it, when in a turn and stuff like that?? | | | | | Joined: Jun 2012 Posts: 1,747 'Bolter | | 'Bolter Joined: Jun 2012 Posts: 1,747 | Read the part about the mount. Original was made to isolate frame flex from the Cab. It was still held in place so it the Cab would not "tilt or move around". New mounting on a modern frame would I think would only require some rubber pads to prevent squeaks. On the slightly newer Cab the center mount in the back was changed to 2 one on each side. Cab floor to the frame rail. Look at the shop manual for 54 to see. 47 Cab mount:http://chevy.oldcarmanualproject.com/shop/1947truck/47ctsm0101.htm Good reading.

I guess I should clarify something.... if i do use the central rear mount it would all be solid (rubber bushing/isolater) removed. I would put some sort of cross member between the frame rails for that cab mount. There would be a rubber pad between mount and cross member.
Or
Put something like a 1/4 plate in floor, build new mounts (will all ready have to do that for the front) that go to frame on outside of rails and have piece of rubber between the mount and the plate.
Thats the two ways I am thinking, just can't decide what would hold up better | | | | | Joined: Apr 2005 Posts: 345 Shop Shark | | Shop Shark Joined: Apr 2005 Posts: 345 | Here is a great link to a thread that one of the builders took the time to write up. He does 8-10 AD swaps per year. He has some information on the actual mounts that he fabricates for the swap. http://67-72chevytrucks.com/vboard/showthread.php?t=632686 | | |
