Rear radius rod install
Hi,
I am installing the rear radius rods on my 1930 coupe. I have a new bolt from Snyder's that looks identical in dimensions to the old chewed one. It seems too long as the cross drilled hole for the cotter pin is beyond the castle nut. I assume this is due to wear in the rod ends. Should I just add a washer? Thanks, Jerry |

Re: Rear radius rod install
I would add one or two flat washers. If you need to use 2 flat washers, I would put one on each side.

The bolt 350700-S should be 3 1/8" long.

Re: Rear radius rod install
This is a problem that has been around for the 25 years I have been involved with Model A's. I have seen it often and do not know the reason for it. However there is a fix, and it should be addressed because it is possible that the nut will bottom out on the threads of the bolt and it will appear tight, but the backing plate is not tight to the axle housing. This will result in the backing plate rocking back and forth with braking and acceleration and it will oblong the mounting holes in the backing plate and ruin it.
For a description of the fix with photos, go to the web site of the Santa Anita A's of Arcadia, California at www.santaanitaas.org. On the home page put your cursor on "Technical Reference", my name will appear below, click on it. A menu of technical articles will appear. Scroll to the heading "Steering", and then to rear backing plates. It is a PDF file you can download and print out. Tom Endy |

Re: Rear radius rod install
You are all correct, the post was about the front of the radius rod. I did not open the photo and look at it. I thought the subject was about the rear backing plate bolts. My error, I apologize, please disregard everything I posted. However, I am not responsible for the indexing on the web site.
