Thumbs up M2 aftermarket crossmember

I purchased a crossmember out of a magazine and would like to make it a rear steer and use a rear steer rack not M2 so it will turn the right direction ,and weld my spring towers on the correct side so my caster will be correct then put my spindles oposite sides with the calipers on the front side .Has anyone did this before with success

this conversion isn't as easy as it sounds, bump steer, toe variations, ackerman all have to be considered. you cuold probably use an early cavalier box but you have to mount it in exactly the right place and the spindle arms would have to be modified to get the correct angles for turning radius and tire scrub (Ackerman). thats why the kits are quicker and most are better.

Ackerman is a term referring to the geometry of a steering system tht allows all 4 wheels on a car to steer in any direction and roll freely and not skid at any time. An important feature is that the steering arms and tie rod are sized and positioned so each wheel turns at the proper (and different from each other) radius. Ackerman dimensions are different for each combination of wheel base length and track width. Thus when you front clip a car or install a MII on a frame, your Ackerman is surely off a bit but is survivable in most circumstances. Putting a steering gear on the opposite side of an x-member is asking it to do something it was never intended to do and may take it completely out of the practical operating range. Not saying it can't be done and I am the world's champion at adapting car parts to strange service but you need to study it carefully B4 attacking that project.
