in my opinion it is unsafe use those univesal steering shaft
RAG joint steering shaft or U-joint steering shaft, it is not the point.
if those steering shaft have not the same factory system to lock steering shaft to the steering gearbox spline shaft.
I wouldn't trust using this locking system, which doesn't use a screw through the groove gear of steering gearbox.
should i just trust the loctite that stops the screw in place?

taking a look around i find this Dorman part 425-177
someone used this part to replace rag-joint steering shaft
in a 91 k1500 and it fit perfect (k1500 is not in Dorman's list of compatible vehicle for this part, but it fit)
i don't know if it will fit later models 95-99 also
if yes it will be my choise

for late models 95-99 you should delete / discart the upper part and insert the factory upper shaft
if this Dorman part has the same GM tube section
from picture it seem the same section
it should be an easy plug and play

there is something else you don't take in consideration
make a zoon in picture below (take from another site, they made an u-joint conversion from a XJ cherokee steering shaft ....)
you can well note the GM gear coupling disegn that is not all circle, but has a square flat spot for good torsional resistance, and a safe screw make this coupling aderent, and anti slip, and screw pass trough the spline, this make a safe and anti-slip coupling with steering gear box.

not a simple screw torqued into the spline, you need at minimum another screw torqued in the square spot, but same it will not result with the same factory safe and streng connection for coupling.

it makes no sense, an upgrade to an oversized u-joint, when you don't make an equally safe and streng connection for coupling

maybe for the forces at play it could be enough... but I still don't like the solution
I found the cherokee XJ steering shaft more suitable...that need modification also to fit my 95
As yet I haven't found something that I feel is right for stronger, more precise steering. until i find the solution i will change the RAG joint with a new one

if you like the Borgeson or Cunnungham machine solution...
may be you can opt for a less expensive solution with the same result

just detach the parts, throw away the old RAG joints and add the new u-joint

# for 94 and erlier model need 2 u-joint - 3/4"-30 Spline X 1" DD Steering u-joint and 3/4" DD x 1"DD u-joint

# for 95 + model only one U-joint 3/4"-30 Spline X 1" DD Steering u-joint

you can find this U-joint everywere for less than $30

would you like add Borgeson U-joint? solid or vibration u-joint? at your choise and deep pocket

Grease and reassemble the steering shaft, reinstall dust boots, and you got factory look

it is not my work...
it is a summary of what is online and which I consider well done, what a DIYer could do with little work, a simple alternative .... for those who prefer to install an universal U-joint.

as mentioned, i will replace the old RAG joint with a new one...quite a complete replacement, not just the rubber composite disc

I'll just get the Cunningham Machine shaft I think. I don't mind the non-stock look.

if you will go with Borgeson or Cunnigham Machine ....you must check where is the flat spot on steering box...usually 12 hours when tires straight

in that position the screw could coincide with the same flat portion position .... and in that portion there is no groove to fix the screw

for fix you must have a screw at 9 or 3 hours position, a 90 degree from flat spot

check it out before

Borgeson or Cunnighan Machine steering shaft, for what i can see from pics in their website or found on the web, ....have only a screw for fix steering shaft on power steering gear box.

both will have the locking screw at 12 o'clock, if installed as a normal replacement.

the u-joint steering shaft could be installed at 180°, in this way the locking screw would be at 6 o'clock, I don't know if there is enough space to fix it underneath, in this case it would be enough to install the U-joint in this position and rotate the steering axle to a position that allows it to be easily fixed.
sure that with one or rather two additional screws they would give a greater sense of security.

the high-strength threadlocker used on these screws would not allow them to be disassembled in case of need for maintenance. it would be very difficult to take them apart.
for this reason they advise if you want to use a threadlocker, to use a light threadlocker (locktite 222 or similar, info from Borgeson website, just open any installation PDF).

in fact it would be really difficult to remove these screws with the hallen head if you used the strong threadlocker, .... if they had a hexagonal head perhaps...

this type of procedure definitely further lowers my faith in this type of mating.

Might fit my 95 as well
removing the upper part, keeping only the lower u-joint and inserting the original upper steering shaft
but I would need to know how long the bottom is and how far the top steering shaft could slide into it

..you told me in Jan
so when i found the part, posted here for you..

istalled Lares Rag joint today, torqued the 2 bolt that hold the rubber disc to 11lbs/ft... deformed the rubber part, but is that torque value they gave for installation
told me you installed the same part...
...also you found this torque value for installation?....had you notice the same rubber disc distorsion?

happy you solved the steering problem
have you take some measures of the lower steering shaft?
I'd be interested to know how long is the lower part from the U-joint of the gearbox to the insert of 1"DD top push rod

if it was long enough i would use the bottom of this steering shaft
