How are you converting to BBP in the front?
How wide is the Dana 35 from mounting surface to mounting surface?
With the 73+ Mopar BBP brakes your 15x7’s with a 4.25” backspace will work with up to a 225/60/15 on most cars. You may also be able to run a 215/65/15, which is right at 26” tall. That’ll be the tallest you can pull off most likely, and it will be tight to the front corner. But if you’re using a different disk brake conversion that may not be accurate.
In the back I’d have to know how wide that Dana 35 is. The taller tires you linked originally will fit, but only if the axle is the right width for those cop wheels.
