hey all, just picked up this 05 6spd with 161k to replace my 01 5spd with 247k on it. its a sport model with rear springs. my 01 is also a sport but has rear air ride. can i swap the rear air ride from the 01 into the 05 and put the springs into the 01? in my searching i only found people with air ride issues or removing air ride to install springs, not the other way around. if there is a thread on it already a link would be appreciated. the pano roof cover also only moves a few inches at a time, i assume this is not how its supposed to work. also wondering if these have the front driveshaft spline issues like the pre facelift ones do. thanks for any help and if theres any other facelift issues i should look out for lmk. ive had my 01 for 110k miles so not new to the e53 platform, just my first facelift one.
