MK Dual Elavator Bellcrank & Pushrod?

[brianyemail-nsrca at yahoo.com]

Ive done this setup but used 4mm tubing instead of the smaller diameter rods, I used very short sleaves even on these. 
 
Wont the smaller rods tend to buckle without a sleeve?

But why do you need a sleeve at all? What do you think the benefits are? I cannot think of any.

I'm experiencing the same thing the Central kit.  The slightest <as in barely visible> bend will bind the rods.  The Teflon from CST works much better.  Wrapping the Teflon with a piece of masking tape where ever you need to glue it works very well. 
  
I was thinking of "lubricating" the rods with some graphite powder when I do the final assembly as I'm somewhat committed at this point.

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 
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.
