18x7 & 18x8 for 69 firebird?

[RBR]

Hi, I'm new to this forum. I'm restoring my 69 bird. I have a fatman front end or (mustang 2). It also has 2in drop spindles. I plan to run 18's with 4.25in bs in the front an 4.5in bs in the rear. Can anyone see any reason they won't fit? I was hoping to order some rims soon. Thank's in advance. Dennis

I forgot to mention it also has the aftermarket control arms and 12in willwood front brakes. Not sure what I'm going to do with the back yet.
