After a lot of thought on this, I FINALLY decided to upgrade Dusty's rear end. I got on the phone yesterday and called MY favorite parts supplier, Classic Parts Of America, and spoke with a VERY knowledgeable and helpful "ANGIE" (X-245) about getting all the right items to complete my upgrade. I ended up ordering the 3.38 to 1 Ring & Pinion gears, the complete installation kit and the differential carrier and rear cover gaskets. Running a stock 235 won't put me in the "fast lane", I know, but the higher ratio should at least give me a better top end (with lower RPM), and save somewhat on gas. Anyone out there that has completed this upgrade, and can pass along their insight on the installation and results?
