I'll have to see what I have, but I know i have a the backing plates... I converted to disk brakes on my truck.... it is a 72 521 backing plate but I believe you have the same differential and axle... h190....

I should have all the other parts too but I may have sold the springs for the ebrake... the only thing that should be different is the wheel cylinders but I was actually using 620 brake parts so again should all work.... metric vs sae....

So I must have sold them but I do have another pair but they are still on the axle.....

The only brake parts I had left were the emergency brake arm and what ever those other 2 parts are....

It would take a minute to extract the backing plates.... I paid to have my others removed doing a disk brake conversion,  i saw an easy to build removal idea but I'd have to make the tool....

Let me know if you need any of these parts....

The 620 backing plates are all the same through '77. 521 plates might work.
