Steering hook up to Must II rack

OK, having a hard time visualizing the geometry of hooking my Must 2 rack to a column, vehicle is a 39 chev pickup. Where the column exits the cab it will not be a straight line to the rack do to engine mount crossmember. Ive heard of using a support bearing and 3 u joints but that puts two weird angles in it. Anybody have a good picture of the setup?

As long as the angle of the joints do not exceed the recommendations of the u-joint manufacturer you should not have a problem. There is the possibility that you may need to use one of the double joints, but that is also not a problem. Check out the web sites for both Borgeson and Flaming River. They should have pictures.

I understand the u joints, but the rack mount points towards the frame at an angle. It seems that one of the shafts would need to be parrallel to the frame. wish i had access to a scanner to draw the pic.


I u had an overhead view it looks like the 2 shafts and the frame would make a "K" pattern

I think just seeing a pic of a completed set up with support bearing would be just the ticket.

You can run the shaft like a snake if you have to but when more than 2 joints are used you have to put in a stationary bearing. Look at Heidts Hot rods web page they also have the stering shafts and couples for almost all columns. Used the 4 times now any you can't believe the bends. You make a mock up with wood dowels the cut the shafts.

The first joint coming off the box is able to bent at 60 degrees and will clear the frame.

If I understand your discription of the steering and the frame forming the letter 'K' , it shouldn't need to if the point where the lines meet is where you are thinking of putting the support bearing.
The support bearing only needs to be mounted to a STRONG bracket,but doesn't have to mount directly to the frame,so as to support the intermediate shaft.
A bracket can be made from the frame that mounts the bearing in the desired location to clear obstacles,and to reduce the angle that the U-joints must lign up to.
I hope this makes sense
I'm not sure how else to explain it.
Good luck

Have you taken out the factory rag joint, and just have the stub coming from the rack? This will give you a little extra room if you have not already done it. Come off the rack with a u-joint and they a short shaft going into the support bearing, after the bearing attach another joint and then a shaft to get close to the column and then another joint to attach to the column. The one at the column you could use one of the vibration damper units that are available, I did not and do not have any problems on my 36.

Thanks guys, those sites helped. Im thinking 3 shafts, 4 joints and 2 support bearings to suck it right up against the frame.

Another question, do i HAVE to run a u joint off the rack or would the damper work just fine. As long as every thing lines up?

I would run a u-joint off of the rack and use one of the combination u-joint/dampers coming off the column.
