Do the new spindles come pre drilled for the larger UCA and tie rod pins?

Is that the factory ( Cast ) spindle ? if so I would be very careful my friend, from all I have read it would seem that welding steel onto cast iron is a no no.
im not a welder or expert just concerned for my forum buddies.
SDHQ said:The first order of business here is to clear up that the factory Raptor spindle is not "Cast Iron", but actually "Cast Steel". Mig welding to cast steel is perfectly acceptable and will easily match the stregnth of the gusset, that being, that proper pre-heatnig and post-cooling (or lack there of) is followed. Pre-heating the spindle to approx. 300-400* with a oxy-acetalene torch or in the oven is the easiest route to do this. Welding in 1" increments is not necessary either, a single continuous pass is ideal. Post-weld cooling should be gradual, if possible wrapping welded spindle in a welding blanket to slow the cooling process is ideal, but not necessary. Leaving spindle at room temperature to cool on its own is perfectly acceptable, just do not quench with water or use a fan or compressed air to speed cooling.
Tig welding can produce a stronger weld, if done so correctly but is not necessary (ER70s-2 or ER80s-d2 tig filler rod will provide plenty of stregnth, although not needed a nickle 99 or supermissle type rod could be used as well).

Also here are a couple more shots of ours on a Raptor and some we have done a little different for some Taco's
I know what I'm doing tomorrow! SDHQ boxes make me happy.
