We used this set up on are built from scratch ratrod. We used the axle mounts but not frame mounts as in our situation they didn't work. We may have to reinforce them later as we think they might not be strong enough. But that is not the products fault it was are mistake as we are learning. I have ordered many parts in the past all have been very satisfied with shipping and products. Keep up the good work!

One size does not fit all.

I bought the TA for my 1930 model A. Only in the Q&A section was it said that the front bracket will not line up parallel to the frame. How much was not mentioned. I figured it must be a minor amount. Reality is approximately 6 degrees. That is excessive. The connecting ends each have a 7 degree angle to the rod to allow a better fit on a more narrow frame but only provided the frame rail is perpendicular to the axle. The model A is at about 6 degrees. This front bracket may work ok with the 3234 but to sell the kit with identical parts for a TA, aside from the bar, is lazy engineering. Perhaps a simple solution is to replace the front (threaded eyelets) with Heim joints. Then you can go ahead and weld those front brackets parallel to the frame rail.

On the stock model A frame(28-31), you will need the 0 degree adjustable ends. 7 degrees is to much. You will not be able to weld the mount straight onto the frame.

Made my frame with 2 x 4 box rails same width as stock model A . Used a widened 910.82831 rear cross member and a 8 in. Maverick rear axle. Careful measurement and it worked out very nice. Angles seemed to be right and it saved a lot of work and fabrication.

Would Recommend

Great simple design. Would definitely use again.

I'm looking for parallel 4 bars with straight ends on booth ends . I see the T/A 3234 bar kit has two sets of pictures, one has straight ends and the other angled. Does the 32-34 bars have the straight ends? If so what would the part number be for just the bars? Thanks Dave
