perhaps the 4age model is stiffer. I have some TRD 4age mounts so I will compare them.

I have decided what I will do; I already have jigged up my custom mounts to suit these in place and just to check when removed the engine no longer sits at the right angle or position. So to stop people having to source these as well with any of the engine adapting brackets that I will sell I will make an oversimplified version of these that can be included.
