You say when you fitted a new one it vastly improved gearchange and idle vibration. How bad was it for you to change.
Engine rocks bit in mine on idle and i believe it to me the dogbone mount as 1st gear is sometimes hard to get.
I've never changed one and don't have a haynes. At a guess it's a quick unbolt and bolt new one in while under the car. Hopefully ahmedRsi will be along to explain the fitment.
On a side note, devnet1 do you have a outside temp gauge in your sport?
Will this mount remove my manifold hitting my subframe?
Also have you got a part number?
Iv just bought one now for £35 including P+P from
