Classic/Antique Car Repair: power steering a/c inline 6 chevy, chevy trucks, burb

Question
Hey,First thanks for any info. I have 2 Chevy trucks with inline 6.

My wife does not drive them because they don't have power steering or A/C.

One is a 72 burb with a 292;the other is a 63 PU with a 250.

I want to add PS and A/C to both and the kits I have seen only have the brackets for SB or BB.

Do you know where I can get the brackets for both PS and A/C for both or either of my trucks.
Thanks,
Joe

 HI ;  I would try ( JC Whitney .com ) they have all types
of kits and stuff , also have you looked at E-Bay . and if you could find a truck in the junk yard you could get all of the parts for it there.and try here -
mysimon.com -  dealsonwheels.com - dealtime.com.   OK !
