Thanks Bob, the KYB 344066 looks much better than the 343127. I wish I would've known that earlier. Since I already have the 343127 I may just see how they do with longer bolts and thick washers. Worst case scenario they don't work and swap them out.

Riki - I considered welding, and I may still do that. I can probably just weld on the thick washers I already have and use it that way. Kind of janky though.

I have changed the mounts put soap on the rubber and twist and pull out soaking on warm water will also help. Washers also work longer square carriage bolts are easy to find if needed

Made some progress tonight. Finally was able to get the rear shocks replaced. Getting the first one of wasn't too bad, just lots of stuff in the way. When I did the rear shocks on my '54 it had no fuel tank or exhaust, so I had nothing but space. Much more crowded under a '56. The second upper shock nut was the devil's work. But I prevailed and finally got it out.



Car is nice and quiet now, and the TL so far seems to work way better. The old shocks that I took out would compress, but never return to extension. They would just stay down. I wonder if the TL was having to fight that?

Finally got the driver's rear drum off. It was seized on the hub and lug bolts. I cleaned up those mounting surfaces, and applied a very light layer of anti seize to the interference spots. The drum surface looked good, as did everything inside. Shoes look new. Reinstalled and readjusted the brakes.



The passenger rear drum came off without a problem. Everything looked good in here, until I looked under the cylinder boots. One side is nice and wet, so I'll be needing to replace the cylinder.



Also compared the cheapo paint markers to the Forney. The paint on the Forney is a little more consistent, but the cheap marker is easier to get straight lines because the tip is smaller. I can rest it against the fold in the metal and use that as a guide. I takes yet strokes per line though, one for the top edge and one for the bottom edge. I'm not done with this panel, but it does look much better so far.



Next up is clear coating the emblems and reinstalling. Then figure out where the leaks are coming from in the master cylinder.

Did you check the fit of the shoes to the drums?
While the passenger side cylinder was wet, was the driver side cylinder clean and dry?
Did you check the cylinder size?

Back on the subject of front shocks, KYB does not sell the lower mounts alone so you can’t change the ones you have. KYB also says that the warranty is only good if the shock is used for an application they have on their list. I haven’t heard what it takes to add to their list.
