65 CUDA suspension help

Just got a 65 cuda and want to upgrade the suspension any ideas? I would also like to change to disc but don't want to spend the grand it cost for a new disc conversion. Any ideas on bolt ons for the cuda? i thnk its 8 front and 9 back if I'm not mistaken. The car is 65 barracuda with original everything. 273 /904 tranny. Not commando. thanks. I have american racing 200s i want to put on car..the front rims are essentially thinner than the rear. any ideas on making them work?
