Radiator shroud and fan

[terryggoround]

I just got my new 6 blade fan to replace my 4 blade fan and also the correct shroud for my 70
Jimmy(po removed the original shroud). I was wondering when I install new fan and shroud
What goes on first the shroud or the fan blade? It looks like there won't be enough room to get to the fan bolts with the shroud on first. Also have a 2 inch spacer. Are there any tricks to holding the blade spacer and pully while trying to line up or get the first bolt started.
Thanks
