Not to dog pile on Ritter but ive got a useless R5 to 727 adapter on my shop wall at over $700 thats not even close to working and if it did the holes are so loose id have to helicoil them like he should of.

I went with another vendor for the right part at 1/3 his price, ive not even moderately impressed with his work, just know he commands top money for everything.
