J, Sorry mate its always me that replies but it does look like your going down a similar route to me with your car.
I used function first transmission mount inserts to take up the sag from the original rubber bushing. I used the yellow one as they said the black would be too hard for the road. if you want it as original as poss and not hardened up then go with the orange. they take about a week to arrive and I think its something like $35 shipping .
Dont use the cheapy ones that are selling over here, a few months ago a few tried them and it got really bad reviews and most took them off. another example of Chinese junk they are making something that looks the same but they dont put in the technical time to understand how or why.I see it all the time eventually we will realise this in the UK and stop buying nasty Chinese goods.
Is your car a tip or man.
I have had the function first ones fitted for about a year and happy with them
