Ordered a gear vendor, help with deciding gears

I'm going on what some people here have reported and the fact that the GV doesn't have "that good" of an OD ratio on paper. There have been a number of people on here through the years disappointed with them. For 3K dollars, you ought not to have to modify the floor, either. JMO

My friend Mike and I put one in his car and we had to cut out and raise a section under the bench seat 1.5 inches for the main gear section so the driveshaft angle was where it was supposed to be.
