Inexpensive side shift firewall bushing solution Options

Chris design if far superior, more robust and simplier

Looks like Patrick racing has a solution too. Might be worth a try also. Look at the bottom of the post about his shift rod and the firewall bushings. They take 3/4in dia shift rods.

The only problem is the bolt flanges on these bushings may run into the lip around the firewall hole on the early tail shift chassis.

Here's the one Patrick uses from Speedway motors: http://www.speedwaymotors.com/Firewall-Mou...-Size,6845.html

An alternate bushing from Speedway would be:

The Patrick tunnel rod has a straight drilled hole where the cone screw goes. (IMG:style_emoticons/default/screwy.gif)
Just one of many things I don't like about their shift linkage products.

But does that mean the $13 spherical bearing from Speedway with the two hole flange won't work?

Chris provides excellent support for his solutions, too.

I would buy from Chris anytime. Except I want to do it myself (Young Frankenstein). I had a '72 and am adding the side shift. So for $8



I did nothing at all to the new shift tube, but I did alter the bearing for lightness and fit - it was 3/4 inch originally. Easy to put the bearing in the lathe and ream it out.



Now if I can finish welding the oil tank for the side and get the motor lifted into place I can try it for real! (IMG:style_emoticons/default/laugh.gif)

That's my ad in the classified. First off, I would recommend Chris's solution first. Years ago before Chris offered these products there was a German guy in southern cal, that worked at a machine shop. He recommended the 3 bolt bearing and was shaving down the stock 73 and later shift rods to 3/4" with a lathe to support the bearing. The solution worked great, but as Chris mentions you have to remove the bearing every time you needed to remove the shift rod. I used double nuts on the rear, to make it easy to remove the bearing from the rear. When going to a 915 gear box, PMS sells a tunnel shift rod that is not adjustable. The adjustment as far as I know is done with the rear shift rod. There rear shift rod is designed for a Wevo. I went with Martin's 916 kit, so I bought Chris's adjustable tunnel shift rod. The adjustable shift rod works great with my 916 trans setup.
