    oh and the spring perch mounting tabs appear to be sufficiently reinforced on the underside so i don't see a problem there.

    however, i did not notice the ball joint mounting flange until you pointed it out, that does look like it could use some work, it would be better if the tubes on the control arm were cut down the center and the mounting flange be welded into the slots, good catch there Ron.

    Those are ready made tabs from chassis works. They are 4140 chromoly steel and have reinforcement at the bottom(see bottom view pic below). They are not bended that's just the angle of the picture. If you look at another photo of the suspension before the coilover you can see they are straight. The curve shape they have was to move the spring perch outward 1/2" in order to change the coil and shock angle.

    No so quick guys. Here is the sketch for the UCA see the tabs and the 3/4" cuts in to the tubes? they reinforce that plate quite well. Why not all the way across the tube? Because the angle of the plate will not allow a cut to be in the center of the tube and it will not have any meat on the tube side to weld at the front. Also my design incorporates a diferent version of mounting instead of the tabs ( see photo below) but for my beta version it was simpler to use chasis works tabs with plenty reinforment in the botom before the final version was finnish. The final ones are build using 4140 square 1" stock with threaded holes for the lower mount.

    ok, that's cool. like i said i didn't even notice it seemed less strong that it should have been until he pointed it out but since you have obviously added those tabs into the tubing it's obvioulsy stronger than it originally seemed. thanks for clarifying :nice:

    One more thing. The final system will be chrome plate using a new process called "GREEN CHROME" it's actually and environmental friendly chrome process from Europe that actually seals the steel preventing rust from coming from the inside out thru the plating of the chrome, it's 1.5 times harder than normal chrome and achieves the "Blue/white effect in the finish.

    Here is the sketch of the ball joint angle

    Well that's what I was wondering, why not just make them straight? By curving them you introduced a twisting force. But I see your final one will incorporate the square stock, so it makes it all moot.

    MAKE YOUR OWN RON MORRIS "ETI COILOVER" SETUP

    Ok guy's, I just came back from Orlando, FL and a package was delivered by UPS and guess what? ,The Ron Morris ETI Coilover setup was sent to me even do i had canceled it. They gave me the $125.00 discount so the came out to be $750.00 + Ship. I will be returning it tomorrow cuz i have already built my own. But for those of you that want to build your Ron Morris replica here is the list of parts needed.

    2 DR3955P (single adjustable) or DDR3955P (double adjustable)
    Poly- 9 1/2 compressed’’- 12 5/8 extended 10 3/4’’--11 1/4 ride height

    2 8CS500 8" extended 2-1/2” I.D. 500# COIL SPRINGS Chrome Plated

    2 BAR500K t-bar

    Plus you have to make the top plate and the bottom reinforment ring for both sides. I had a complete set build by a machine shop that i have no use for them now.

    Sorry for not posting pic's but lost my camera and GPS in Orlando last saturday. I will borrow my son's camera before i ship them back to post some pic's.

    how does a coil over on top of the UCA be much different than a regular spring? I would think a coil over attached to the LCA would be much better, wouldn't it take stress off the spindle and work better?

    i agree a coilover mounted on the LCA is a better design but the C/O mounter on the UCA still allows a height adjustment. a UCA mounted spring has a wheel rate that is 50% of the spring rate and a LCA mounted spring has a wheel rate of 85% of the spring rate
