the part numbers of the spacers were: left 66.10.00 / right 66.20.00. the assumption by uai that this did not exist during the production of the ideal seat "S" is unfortunately also wrong. of course you can mount an ideal s on it. but these spacers only fit on some brackets (very flat - like in your photo)- as far as I know vw models - is also in your pictured description.


Hope I could help a bit.
