8 3/4 axels???

No sweat Fishy.

I pulled the 25" axles out of the air to give you an idea of total length.

If you minitub, ideally, get the wheels and tires you want to run before cutting the rear. Getting a rear that's already cut then finding wheels that fit right is a pain. To suggest a width for minitubbed... Anything from about 46-47" to 57.5" total drum to drum will work depending on wheel width and backspace.

Here's a good page with correct stock lengths...
