Hey Guys, I need your help! I ordered a DSS driveshaft and went to my mechanic to install the new driveshaft and J&M UCA. The install of the UCA went okay, but the driveshaft does not fit! We ended up dropping the exhaust, dropping the transmission mounts and finally got it SQUEEZED in between the pinion shaft and transmission output shaft. The shaft is so tight it's ridiculous! And the dimension at the pinion spacer and shaft end is only 2-7/8". DSS paperwork says it should be 3-1/4 to 3-3/4" DSS is closed right now so I'm looking for help. One question I have, does the pinion spacer go all the way into the pinion flange? Mine sticks out about 1/4". Is this normal? Seems to be fully seated. Could this be my problem?
