If you’re asking about the TH200C 3 speed it worked out good. No major clearance issues. There was some clearancing necessary with a hammer and or porta-power in the tunnel as I think I talk about earlier in this thread but no cutting. Not extreme. Floor console goes back in. Also clearanced/grinding the case of the trans here and there. Actually using the stock linkage in the car. It locks out Park, hits the gears properly, and locks out first (since that is where reverse was) which is pretty nice. It does not lock out reverse. You shift from Drive to Neutral to Reverse without a lockout. Had to fab up a simple below floor linkage from the stock arm to the new trans.
If you’re talking about the 200R4 someone else can answer.
