Ramjet is in Sun Valley off San Fer and Tuxford while Currie is in Paramount. I installed a 4.44 ring and pinion on my RX-3. It is whining and I have taken it apart twice already. I'm wondering if anyone has any experience with the above shops. Or if you know any backyard mechanic who can do it professionally, lmk. I have other good sets such as 3.7, 3.9 and 4.78 but I feel that a 4.44 is more appropriate with my driving habit since I'm running a 13-B bridge

thanks
