This may not look like I've done a lot, but, I have. I've had the Dakota crossmember out then in again three times and the F-body member in and out twice taking measurements. I'd laid a long straight edge across the F-body k-frame and using the grease fittings on top of the upper ball joint, marked out the axle centerline. I had to do this multiple times to make sure I got it right. I did the same with the Dakota crossmember out of the car. Once I got it all marked out to where I thought it should be, I put the Dak one back in. Before I did that, I had to trim a piece of the frame where the drivers side rear k-frame mounting goes. Once trimmed, it slipped in with some shoving. Things I have learned. F-body frame rails are not symetric. The drivers side rail bows in slightly where the steering box coupler goes. I'll have to do something about that later. Right now, it's just sitting there (again) marked out. Fits well. No major cutting and welding done yet.
