There are 2 types of tranny mounts... A
A: the big crossmember( which has a rubber bushing PRESSED into it... You can't replace the bushing, have to buy the whole new part..) 70 bucks at mazdatrix I think..
B: Then there are (2) "Y-block mounts" up above that are like 10 bucks each...


shipping probably about 4-5 business days, unless you pay more for quicker shipping.. that's to Omaha NE at least.. not sure about toronto

are you not replacing the crossmember mount? That is the one that usually goes bad.. The others are just Rubber blocks basically...
The crossmember has a rubber bushing in the middle that can acually TEAR apart, and once that happens you will notice some vibration at idle... Only way to replace the rubber bushing is to replace the whole cross member... Check the crossmember when you replace the Yblock mounts..
