That smaller one doesn't look like it'll fit, as I don't have the space for the pipework to clear the rad. I got some measurements for the bigger one and it'll fit perfect, as the end tanks will wrap around my rad. Thats what i'll try and get. I don't even know what model it came off, so i'm going to struggle.
Do you know what it was off when you originally got it? Where did you find one for £30?
My current IC is a Volvo 940 but i've split it, I can get another for £30, but i'm thinking i'll kill another one too.
