Gear box engine gasket/seal

Yes if its the rear crank shaft seal I did mine a couple of months ago after it suddenly decided to develop a leak. Pretty easy to do, as above props off seperate gearbox from engine, with my 2" body lift I made enough room to work in by just sliding gearbox back as far as it would go. Remove clutch and flywheel and the seal is in a half moon plate which I decided to remove although apparently you can leave it in situe . The plate is part of the rear sump seal but easy enough to reseal and after reasembly no oil leak problems since. Pretty time consuming 1st time you do it but if your methodical shouldnt run into any problems. No special tools needed either
