Replacing Drums and Shoes on 69 Dart

I just did the scarebird conversion.
After doing a lemons rally with the 9” drums (tail of the dragon too)
If the Rona ever passes you can check out my darts brakes to see if you like them. I’m in fburg too

Would definitely like to check it out. How difficult was the conversion and where did you source the parts from? I honestly haven’t investigated that possibility with my Dart at this point, but it does occasionally cross my mind.
