The plan for the front was a 4 - 4.5" static drop with a disc brake conversion thrown in for good measure. After "researching" many of the posts on this forum I eventually went for 2" drop spindles and 2" lower springs. Living in the UK I can't simply go to my local auto parts store and pick up a few parts if I need them, so for this reason I've always tended to buy kits and the most comprehensive ones I can find. This spindle kit came from Tom's Classics and includes McGaughy's 2" drop spindles and 12" drilled and slotted rotors.
The Spring kit is from POL and includes 2" drop springs front 4" rear and comes with matching shocks and hardware. Both kits were sourced through Langy's Rod Shop here in the UK.
The "spot the difference" picture
The springs and spindles were assembled using the "red neck" spring compressor (a trolley jack) and were a perfect fit on the new ball joints.
