GSR/EVO I-III OWNERS - LOOK HERE
In the early days most Prothane 1G DSM/Eclipse kits came with 3 full solid inserts and 1 dodgey little insert (4 in total). The dodgey little half-assed insert was meant for the Eclipse's front transmission mount on the crossmember behind the radiator. However this little mount didn't suit the GSR/EVO.
Over the following years it appears that the kit offerings by suppliers have somewhat differed and the old half assed insert was abolished and a new solid 13-505 insert was produced (which still doesn't suit a GSR/EVO anyway). But for some reason, and I suspect it to be due to consumer and seller confusion between 1G/2G/V6 Eclipse, Talons, Lasers, Manual/Auto transmission and FWD/AWD offerings, the naming and sizes of some of the part numbers included in kits became too confusing for GSR/EVO owners to know exactly what to buy.
Ultimately, for GSR/EVO owners, it has now been determined that you are better off to buy your inserts individually to ensure you get the correct ones!!
You will need 4 inserts in total.
A good place to buy them individually would be on EBay.
1. Transmission mount insert "right upper" (aka the mount at the top of the gearbox) Manual transmission
I have confirmed this mount to have an 80mm inner diameter with a 50mm inner thickness.
The part number for this is a 13-501.
When you install this insert it ends up being 70mm wide. However the OEM gearbox bracket width is 80mm wide. Therefore you have to add the 2 x oem flat black rubber dampers on either side of the mount to make up the full 80mm requirement. Have a look at the attached pic of an OEM EVO III gearbox bracket below. You can see the black rubber dampers on either end of the insert. You need to install these when you install the 13-501 Prothane insert.
2. Engine mount insert "front" (aka the front mount on the crossmember behind the radiator) Manual transmission
I have confirmed this mount to have an 80mm inner diameter with a 40mm inner thickness.
Currently we are purchasing the 13-501 mount for this one. Then slicing 5mm off each half to make it 40mm thick.
I will check with Prothane now if they have an off the shelf item with 40mm inner thickness to save any modifications, then update this thread.
3. Engine mount insert "left upper" (aka the big engine mount next to the timing belt cover)
I have confirmed this mount to have an 80mm inner diameter with a 50mm thickness.
The part number for this is a 13-501.
4. Engine mount insert "rear" (aka the rear mount on the crossmember closest to the firewall) Manual transmission
I have confirmed this mount to have a 70mm inner diameter with a 40mm inner thickness.
The part number for this is a 13-506.

1989-1992 GVR4 OWNERS - LOOK HERE
There used to be a 89-92 Galant VR4 (GVR4) kit available but unfortunately it has since disappeared. Maybe because some distributors/ workshops were putting the kits together themselves and selling them in their stores/Ebay (Prothane company themselves didn't sell a GVR4 kit and they are not listed in the Prothane catalog range). Whether these distributors simply have not bothered with making the kits up anymore, had complaints about suitability between models, or possibly even had consumer confusion with the larger V6 Galant VR4, who knows? But whatever the reasons, they've since disappeared off our internet search engines and we need to get a record of what part numbers were in those GVR4 kits!!
Wade (VR42LT) has volunteered to take some measurements of all his oem GVR4 mount inserts. They are currently not installed in the car which makes the job a hell of a lot easier to do :thumbsup:
OK UPDATE: (ALSO SEE ATTACHED PIC OF GVR4 MOUNTS)
1. Front Roller Stopper (the mount in between the radiator and the engine block)
Confirmed this mount to have an 70mm inner diameter with a 40mm inner thickness.
The part number for this is a 13-506
2. Top Engine Mount insert (the big engine mount next to the timing belt cover)
Confirmed this mount to have a 90mm inner diameter with a 50mm inner thickness.
The part number for this is a 13-503
3. Rear Gearbox Mount (the mount at the back of the gearbox against the chassis rail)
Confirmed this mount to have an 80mm inner diameter with a 50mm inner thickness.
The part number for this is a 13-501
4. Rear Roller Stopper (the mount nearest to the firewall under the intake manifold)
I have confirmed this mount to have a 70mm inner diameter with a 40mm inner thickness.
The part number for this is a 13-506
