Transmission mount bracket for 1800, M41 J Type models. This is available for the first time! It is often missed when doing a BW35 (automatic) to M41 conversion. The BW35 and the M41D (older overdrive unit) use a different mount. This mount raises the rear of the transmission to its correct height to prevent the driveshaft from rubbing on the bottom of the tunnel. It is used on all M41 J installations in any year 1800.
