So which one is better/easier to install?
Rear Main Seal - rubber (see notes) -- 4519S
or
Rear Main Seal - rope -- 6100?

Edit: On another note, The clutch is quite bad. found this one on ebay: http://www.ebay.com/itm/AUTOCOM-ECO...ruck&hash=item460d5352bb&vxp=mtr

Only one i found. But it says it's only compitable with the 3.8L engine, and not the 3.5L. Is there a diffrence? Where could i buy a new clutch otherwise?
