tranny cross member help
Here are some pics of my problem. What could I use to take up the space? It's 2 inches that I need. I guess a piece of 2 inch square tubing would work? Anyone have some other ideas?

Re: tranny cross member help
The square tubing is a good idea. Or maybe weld a piece or angle iron inside frame to bolt crossmember. Then theres always spacers like some chevy trucks used.

The angle iron is a good idea. Then I wouldn't have to have 2 1/2 to 3 inch bolts going all the way down. I guess the easiest would be the spacers.

Re: tranny cross member help
From an engineering standpoint, angle bolted to the frame will be best. If you use tubing, I would recommend using short bolts, bolting the tube to the frame and the tube to the crossmember. Long bolts through the tube become a major problem with shear loads. Meaning that if you bump into something too hard you will probably break a bolt.

Re: tranny cross member help
Looks like a problem to me. With the C channel is sitting atop the angle bracket, there is a hollow under the bolts. Bascially, it can't be tightened, it will just collapse. Maybe it will feel tight when you put it together, but with use it will flex and settle, and always be coming loose.
Some spacers under the bolts to take up the space might be good enought. I'd rather see the angle brackets shortened to fit up inside the C channel, and raised appropriately so it is metal-to-metal at the bolts. |

Re: tranny cross member help
Is that an NP208?
If it is there are two adapters, a 'tall' and a 'short'.
