It is confirmed that I bought the wrong roller bracket from MVP, however I am fairly certain I can grind it down to match the angle of the 1JZ. I will try it and post!

Hey Man, I modify oil pumps for the supra community. I drill out both of the bypasses 1mm larger, blend some casting marks, and shim the spring 3mm, and add allen hardware to the rear plate with red locktite (my last motor that plate seperated from the oil pump and all my oil was bypassing into the pan.(12psi on my proefi gauge)
My car now sits at 60psi idle cold, 40psi hot (40wt) and is at about 90psi when i hit 9000rpm. I WOULD HIGHLY recommend not removing that spring/bolt combo. Not only with the oil pump just keep bypassing oil back into the pan through the top breather, but it may bypasses too much oil to actually hurt or lower oil pressure at idle. Leave it in and add 3mm worth of washers. cant go wrong, ive done about 20 of them,
Good to hear on the idler. Modifying should work.
