6 hours! But took it out and in 3 times...the cable socket on repaired old carrier just kept popping out of joint! So used spare cable from oem carrier .much tighter fit but door wouldnt open. Finally cable from broken i removed worked fine...vapour barrier tears courtesy of prior mechanic fixes, i secured up with aluminum adhesive tape....and whilst in the guts of door replaced window clip and did a st.steel zip tie re enforce as i think the sliding plates were on the way out....totally shattered as had stress.of odd weather threatening whole operation. Next time i will have a new one handy and sure that up with a cable tie...darn cable totally threw me..all goodvthough in the end...i will buy a carrier for front passenger side now. Ps heat undid the top plastic inner part of door from the door card....so had to go get some epoxy resin to sure that up too...glue gun may have worked but didnt use...
