Corsa-B.uk - Vauxhall, Opel and Holden Corsa B Owners Club

i have put a digi dash in my corsa but i have only got 3 bulb holders for the left/right indicators and the handbrake. i have tried to get some from vauxhall but they are obsolete and all the scrap yards ive been to dont seem to have any either. is there another vehicle that has the same type of bulb holders that i can put in my digi dash?
the type im after are square and just push in, all i can find are round twist in ones.

any help would be great as im pulling all my hair out at the mo

has anybody got any they want to sell even? if unsure what im on about ill upload a picture if that helps
