So ... It's time to rehab the front end on my 69. Currently it's all stock minus a fast ratio box. I'm going to be installing hotchkis SBC 2in drop springs, global west off set crossshafts, del-a-lum upper and lower bushings and new ball joints. I've hemmed and hawed over this and feel pretty confident that I've nailed the right parts. Currently my alignment is at factory settings (I.e. Castor at 0 +\-). The car is numbers matching and I'm the second owner. There are a few mods here and there but no massive departures from stock. I've been reasearching the guldstrand mod (g-mod) (drilling my upper control arm perches) for awhile and while I see the value on paper I'm looking for someone who has done it and can say that it's worth drilling and grinding out the subframe and control arms on a numbers matching car. Or will adding the cross shafts bushings and doping the alignment (castor to +4 with shims) be just as good. Any advice will be greatly appreciated.
