As noted in another response, the part is relatively inexpensive at the dealer. You might also try an online supplier like Swedish Engineering who sells Volvo parts at a discount. You might also try Erie Volvo (erievovo.com) who specializes in used Volvo parts. By the time you pay for shipping, a small part like the one you are looking for, you are probably better going to the dealer. For other items, it is worth checking other sources.

Good Luck.
