hi, ive been advised my sump is cracked and needs replacing. ive got someone to replace it as long as i supply it. im looking at 2nd hand ones which seem to be scarce. the trouble is i dont know if i need an alloy or steel sump. i think it may be linked to whether their is a/c or not, my 406 is a 1999 1.9 lx dt with a/c. thanks in advance for any help, im not too clued up on these things!
