I had no idea Harland Sharp made rockers for Buicks. They seem quite pricey but the Olds guys like 'em. http://cgi.ebay.com/ebaymotors/HARL...ewItemQQcategoryZ33624QQitemZ8067361213QQrdZ1
You wont need to spend the $$$$ for them unless you are all out racing. The T&D's that TA and Poston sell work fine at $735.00 That's a great price on them. Harland Sharp is a 1/2 hour drive from me. I went there and got a price of almost $1100 for them.
