I'm swapping a c4 trans into my 2wd 85 f150 (351w) that has a 4 speed granny geared standard in it currently. Will I be able to use my same crossmember or are there any aftermarket options (double hump style) that would better suit my long tube headers? Thanks

 

Well I got a double hump CM out of a town-car or crown vic, I'll have to cut it down to fit but oh well. The humps seem to match well with the headers for clearance, if anyone else is looking to do this.

 

Let it be noted that you need to make sure to triple measure the alignment of the drivetrain in reference to the frame before cutting. I cut my first one with the humps/trans mount to be dead center of the frame, and low and behold the entire drivetrain sets off center about 2" favoring the passenger side. So when I installed the CM it fit the frame but nothing lined up at all.
Luckily it was just a $20 mistake. But hopefully this will help someone in the future.

 

Good point to mention. Most people don't realize that the driveline is off center.

 

Yep, I don't know what all years this would effect but it was definitely a set back for me.
