Finally got my 'Burb

[Dragsterbus]

Hi , well i finally picked up my 69 suburban, it's a 350 4 speed manual, i was sad to see my '92 C1500 ext cab go but i'm really pleased with the suburban,
My plans are
1, Lower it (a lot)
2 , disc brakes on the front and convert from 8 stud to 5 on 5"
3, probably swap out the rear axle to get the 5 on 5 wheel pattern and to increase the gear ratio (very slow at the mo and really thirsty)
4, replace the top tailgate which is made of fibreglass/filler/newspaper etc
5, new bumper and grill, the previous owner crashed it (drum brakes and no booster)
apart from these bits it's really good, the vinyl roof will have to go too,

right question time, are the drop spindles the same for the 1/2 ton as the 3/4 ton ?
Which disc brakes do you use with the dropped spindles ? (i've got some C1500 5 on 5" ones already)
Is anyone making replacement top tailgates or shall i look for a s/h one ?
who does those cool 8 lug slot mags ?

Thanks for any help !
