Re: Crossmember
There are 2 crossmembers - one removable (bolt-on) for the xsmn mounting and one fixed (part of the unibody). You need both..... but both can be modified to fit your personal installation requirements.
Some folks like to make the fixed xmbr a bolt in piece to facilitate engine/xsmn removal - but it is there for body integrity, so don't skimp. |

Re: Crossmember
Bill, are the end plates 3/16" ? The base material isn't all that thick so I'm assuming there is no need in over engineering here.

Re: Crossmember
Guys, before you jump in and start cutting, just bear in mind that it will be almost impossible to regain what is lost, and most guys find they can remove the transmission with the stock crossmember in place.

Quote: +1 My original crossmember has never cramped my style at all... and I reckon I've got my transmission mounted about as far rearward as anyone. |
Re: Crossmember
The plates are 1/4" The may point to consider is the holes for the bolts need to be just large enough for the bolt to fit.
The force is not on the plates, it is concentrated on the center of the plate via the tube on each side. The bolts hold the plates together. The difference is that I can remove the trans faster and easier. As for stiffeness, there are no issues with mine. I have done this since my first MGB race car back in 1971. There is no difference between this crossmember and any other unit construction body which is wider, longer and less crossmembers. When I service my car I use to jacks on each side, while doing this there is not flex on the body. Doors can be open the same. I have tried without the crossmember and the doors have just a litle drag on them on the RD and nothing on the GT.. It works for me, but it may not work for anyone else for what ever reason, which I am sure is valid to them. I just know what I have experience. I am not trying to convince anyone to do anything, just sharing what has worked for me. |
