Alfa Romeo 147 (2000 - 2010), 156 (1997 - 2007), GT (2003 - 2010)Front Lower Wishbone Rear BushWe have found that there can be a difference in the end-pin diameter on some wishbones, especially non-genuine replacements. We supply PFF1-812 with the more popular 20mm bore sleeve, but we have seen wishbones with 21.3mm end pins. If you find the ones supplied are incorrect for your vehicle, please contact us by email with the dimensions required and we will send you a set of the correct sized sleeves free of charge. PFF1-812 also comes with different sized adaptor rings to suit different sized brackets. Use the smaller ring (1-802B) with the aluminium bracket and the larger ring (1-802C) with the pressed steel bracket.
