MK Dual Elavator Bellcrank & Pushrod?

[Archie Stafford]

Gray,
 
The pushrods they are talking about are the pushrods that Troy Newman
outlined a few years ago for the elevator.  The pushrod is VERY thin, and
over that distance has to be in a tube.  These are not the 3/16" or whatever
rods that are also used sometimes, these are much smaller.  I do not know
what the actual diameter is.

Gray, how would you set them up without a sleeve? I like this setup and a
better way to install it would be great. Can you elaborate on your
statement. Thanks

Speaking of the CF push rod set ups, I would like to share a little info. I
just finished installing my second CF. elev. pushrod assem. in a Impact, the
first was in my Majestic. In the Majestic I got the DEPS setup from CST seen
here  <http://www.cstsales.com/CCPush-rodKits.htm>
http://www.cstsales.com/CCPush-rodKits.htm 
This kit comes with a thin walled Teflon outer case and even with a slight
bow or arc in the assem. the system remains Very friction free. 
For the Impact I purchased the kit from Central and it comes with plastic
outer cases and these were difficult to get smooth and friction free, the
slightest bend or arc made the movement very stiff and as a matter of fact,
I could not even use them and ended up using hollow CF. rod for the outer
case which worked very well but slight bends or arcs are out of the
question. Just my personal experience, yours may differ.

I never understood why they supply a sleeve.  Makes no sense when using a CF
rod. Teflon is also heavy, and bonds very poorly, if at all.
