Dear fans of V-8 Buick performance, This morning Hemmings has an e-news article on the GM A-body platform. There isn't all that much new in it, although there are a few helpful tricks. What is of much greater interest to us Buick types is a reference to differential cover/girdle from TA Performance (part number 1808). Here is a link to the article: https://www.hemmings.com/blog/article/inside-information/ You'll find the TA-Performance reference around 2/3 to 3/4 into the article. Congratulations to the Mike, Sherri, Michael, Jr., and the whole TA-Performance team!! Cheers, Edouard
