Driveshaft grease seal

I think I have at least 3.5 to 4 inches. The info u sent me about measuring the springs is what I went by when I was trying to figure it out. I went offroading one time so far but I do plan on more.
 
Someone has a picture of a front driveshaft on here that has the end all bent up because it was on a lifted Jeep. You can do what you want just letting you know.
 
I found it.

And I do appreciate that. That's why I became a member here. I know I'll get good info from knowledgeable people with experience. Thank you very much.
