Fitted one to my 09 D22 2.5 Ltr
it was a DIY job at work with 3mm mild steel, a bender and a plasma cutter.
I did not cut out the oil drain holes, and the holes at the rear are different to the drawing due to the cross bar not being flat.
The reason I did not cut out the holes is because, to refill the diff you have to take the plate off any way, so kinda pointless having the hole, and the hole for the sump on this drawing does not match the sump on the 09 D22 2.5 ltr, which left it as a massive point where anything could enter and puncture your sump.
Length, Width, bend angles all suit the Thai Built d22's, just a little modifications to for the holes.
