how much does it shorten the bars, what effect does it have in the rough conditions, what bar angle do the holes need to be located?

That kit wouldn't work. The holes are 1/2" on the 7-hole plates. 5/8" holes were used on the 4-hole plates.
Mastersbilt will sell you the hardware if you want to weld everything up yourself. Unless you know what you're doing, I wouldn't go fabricating the plates since you won't know where the holes need to be. It doesn't change anything in terms of bar length, just gives you more adjustability.
