my PDR twins came with a bracket. the flat stock(bracket) is pre-bent but needs cut to length ,,drilled to line up with a bolt hole in the block and welded to the bottom turbo oil drain.
i don't have a mig welder but as soon as i get access to one the bracket will get installed.
like bandit1 says,,it's a lot of weight hanging off 4 studs. hey!!,,i'm the one who told him that :-laf
i talked to a few twin builders and it's about 50/50 on having the bracket.
