power steering on 350 v8

[jtm]

got the disc brakes done on my '64 fleetside. was goiing to do the power steering at the same time but the kit i bought does not have a bracket on it that will work on my engine...has anyone put a power steering kit in on a 350 v8 (mid 80's range)...there are two bosses on the bottom where it theoretically would go but requires drilling and tapping. want to avoid that if possible as I do not think it would hold real well, dont want ot crack the block. has anyone seen a bracket that would mount via the manifold perhaps?
