Universal steering couplers

So i guess saving steering u-joints from cars that have two was a good idea after all. the u joint in the engine bay fails, the one under dash is like new.
some are slip-shaft style so i have the necessary parts to weld in. Or i will mill off the splined end and weld it to the better u-joint.
Did that on a dodge pickup about 20 years ago,still there still perfect.
