I would like to know the difference between two products: 1. https://www.alza.cz/EN/auto/schneider-predni-stahovacka-mechanizmus-elektrickeho-systemu-bez-motoru-4-5dv-l-pro-renault-meg-d9890845.htm 2 https://www.alza.cz/EN/auto/schneider-predni-stahovacka-mechanizmus-elektrickeho-systemu-bez-motoru-2-3dv-l-pro-renault-meg-d9890672.htm They both seem the same, but have very different prices.
