No, different attachment dimensions.
yes!
does a VW golf auto transmission interchange with ajetta?
No. Different pattern
the ceiling wouldn't fit because it would be a little too big, if you meant the actual glass sunroof it will definitely fit any mk3 model including jetta/golf/gti for sure.
No different exhaust lengths and bends that's like saying can a limo exhaust fit on a pinto
No, none of those will fit without extensive fabrication.
yes
Yes, the body parts of a 200 Jetta GLS can fit on a 2002 Jetta GLS with little fabrication.
Will rims from an 09 Toyota camery fit an 05 jetta
Yes
No. The only compressor that will fit your 2000 Jetta is one with the same part number as your current one. They are completely engine-specific.
No, not without modifications.
