1at generation brakes
 

I'm new to the forum. I recently acquired a '68 SS and was considering upgrading the rear drums to disc. #! I was hoping to get feedback from any one thats made the upgrade and if it's an improvment and to what degree. Also, what kit does the best job as I've seen3-4 dirrerennt kits.
I'm also changing out the "14x6 rims to "15x7 wheels. What tire sizes would be preferable 225 or 235? Is ther enough clearance for these?

Thanks for your feedback
