5/7" drop, possible w/o air??

[Gixxerboy]

I see all about the 4/6 drop, but in my eyes it just aint enough, and air ride in my thoughts is too much money/time/effort to be altering my frame a whole bunch, for now atleast.

I was wondering how some would be able to put together a 5/7" drop. If so where could someone get the parts or if a kit is available.

if not then where is the best place to buy the 4/6" drop
