This is one of the single most important installations to choose right-not based only on price. I'd just avoid Mac's altogether regardless of price. Start by finding out who your manufacturer is. Why do you want helper springs? To me, that sounds like you have low expectations for the spring rate of the spring you're installing. also anyone know where I can get helper springs for the back of it. looking to get my rear end raised up a little. does anyone know why the prices are so different, they are both rated the same. bird nest wants basically 600 dollars for a new pair but larry's wants 137.65 a piece for them.
they both list new leaf springs for a 66 thunderbird but the prices are as different as night and day. I have a question about new leaf springs, I have a catalog for the bird nest which is macs auto parts and a catalog from larry's thunderbird and mustang parts.
