Trusty auto-one sadly don't have a part listing for an MA61 gearbox mount.
They do however have a listing for an RA65 gearbox mount ($70). I want to know if they are the same. Not similar - they need to be identical. I don't want to use the RA65 one if it isn't going to be as strong, or if a slight adjustment will need to be made. When it comes down to it I'd rather pay the extra $90 and get a toyota genuine one. Alternatively, if the RA65 & MA61 gearbox mounts are totally identical in every way, then it'd be foolish not to get the cheaper RA65 one.
