OK , that is more in line with what I’m trying to find out. Thanks for answering. I still would like to get other thoughts and am kinda leaning towards the 18 spline Passon OD kit.
Don't do the Passing OD 18 spline kit. I did it and the OD ratio is only .80, it isn't significant enough in my opinion. Plus I couldn't downshift into 2nd consistently, so I tried to talk to Passon about it and I didn't get anywhere. I talked to Dan at Brewers and he said he knew those gears were an issue, he could fix it, but at that point I was done. I ended up selling the car, spent ten years getting it exactly the way I thought l wanted it, but it wasn't what I thought and the OD kit was a major part of that. Just too much time and money spent to do it over. Just fell out of love.
If I could do it again, I'd keep the 23 spine 4 speed with a 3.23 gear and just cruise.
