4.5 / 5 drop

[lax54650]

my 68 short step is tore apart would like opinions. i bought 2-4 drop springs then purchaced 2 1/2 spindles 2+2.5= 4 1/2 front would puting lowering blocks in rear say 1" look ok? i am not crazy about using to big of blocks. scrub issues.
also money now is huge issue. (wife left me with my house pmnt and my truck GOOD BYE) should i sell my parts 6 lug rotors, spindles calipers prop vavle. and just put springs in and fix drum brakes to get it on road. cant really afford all new ball joints ends and bearings. (spindles are for 72)

basicly question is...is 4 1/2 front too low with 4" rear springs? if not will 1" block level it out enough? will front crossmember be too low at 4.5? the wheels i have are aluminum with 265 70 15 tires.
