okay guys please analyze if i am doing allrite ??
I went on LUK website

Schaeffler Automotive Aftermarket ? Online Catalogue, Product: Flywheel

There on the right top search button so i wrote mercedes oem numbers there and it gave me their alternatives

so for flywheel a1120301305 search result was above page than i search on ebay.it for 415 0118 10 Flywheel LuK DMF and found this flywheel economic as possible

LuK 415 0118 10 Schwungrad MERCEDES-BENZ | eBay

in this ad its written also mercedes oem part number Referenznummer(n) OE: 1120301305

So secondly i searched for a0002541608 result was
Schaeffler Automotive Aftermarket ? Online Catalogue, Product: Central Slave Cylinder, clutch

accordingly when i searched for this on ebay 510 0035 10 Central Slave Cylinder, clutch

i found this this https://www.ebay.it/itm/Zentralausru...AAAOSwUKxYjx4a

its different brand than luk but it have mercedes referance on his page Referenznummer(n) OE: 0002541608

Oem are matching does brand matching matter ?

so lastly plates searched for on luk webpage a0002526305 result was 324 0229 10 Clutch Disc

searched on ebay https://www.ebay.it/sch/i.html?_from...022910&_sop=15

and chosen one economic one between again different brand

BOHRMANN Kupplungssatz ohne Ausrücklager für Benz V-Klasse Vito 638 | eBay

and on his page there isnt our exacly referance but from luk page says there is 3 article matching to luk general in this page case luk general one is on the referances 324022910 and also from mercedes following referance as it states also on luk webpage
A 000 252 30 05

its been a hell of a ride as kit isnt available anymore by luk europe non shop have in their stock so have to collect them by one by can they match ??

Not bought any of it yet as still wanna check the flywheel with mechanic if he can fix would save me 500 but he wasnt seem positive for it today if he could fix why he would make me buy new one
