AHH5832   TC.A.22   Rubber -front engine mounting (L/H) -(engine mounting, Twin Cam)

Fits left side of MGA Twin Cam (and "Deluxe" cars). Can also fit left side of any pushrod engine MGA and left side of MGB 1962-1974. This part is physically identical to AHH5028 for the pushrod engine cars, but has been assigned a different part number unique to the Twin Cam. I might speculate that it was originally intended to have different durometer rubber, possibly intended to be a little stiffer for the heavier twin cam engine with more power (more torque). So far no one has produced the original factory drawings, so this may forever remain a mystery. Meanwhile, many of the replacement parts suppliers use a single part number to serve both pushrod and twin cam engines. Notice alternate part numbers below.
