Rebuilding drott 4in1 from 450

[1BB]

Doing a total rebuild on this bucket. The cutting edges are severly worn. I was wondering if anybody had any measurements on the inside weld on wear edge of the clamshell part. I am guessing it to be around 7 inches wide with a small bevel to it so it sits tight to the bolt on scraper edge. It looks to also be 1/2 inch thick. Case parts no longer stock this part. Hoping for some help on this one it's the last major part to replace on this bucket. Hoping to clear out the brush this spring.
