    Motor Mounts

    The US motor mounts are not available. The mounts for the US Manta are different than the versions on the European versions.

    The European Manta mounts are the version similar to the '71-73 US cars. The '74-75 engine cross members have a small bracket welded on to accept the bolts for the that specific US mount. The original '71-73 mounting hole is still present on the cross member beneath the bracket added for the '74-75 mount. The change in style was designed to keep the motor from leaping into the radiator if the mount broke, or so the speculation has it.

    So if one removed the welded bracket the early mount could be substituted with no other modifications?

    Seen that with NEW mounts. Fan blades didn't clear the fan shroud and busted the radiator too under a hard brake.
    Needs a 2dr Ascona, everyone else has one.

    Searched this up after looking at the 74 Rallye Gold Manta that's for sale on E Bay where it says "could use a motor mount replaced". Good luck finding one. Harold asked a question earlier in this thread about removing some of the 74 bracket to use an earlier mount but I saw no reply to that question.

    I believe Bob or someone had a tech tip on replacing the mounts with a universal Poly mount for a 350 or something like that.. Been a while.

    All the details for the later Manta/Ascona replacement mounts are here: 24V Ascona A Conversion: Motor Installation

    I used Energy Suspension tranny mounts.

    Energy Suspension transmission mounts were used in place of the Opel motor mounts. They were roughly located using a 1/4 inch plate bolted to the blocks motor mount holes.



    Motor mount to crossmember brackets were made from 1/4 x 2 inch flat stock. Countersunk M-10 flat head socket cap screws secured the rear of the bracket and the mount lined up and secured using the front hole.
