Need Hollander Interchange help--'63 Riviera Steering Box

I need a power steering box for a '63 Riviera. Can someone look it up and tell me what interchanges? I have a book, but it only goes back to '65.

 

#654 #5689662.........59 le sabre w/std trans,late 59 w/at,59 electra 225 w/at,60-63 all except buick special////hope this helps

 

Wow--sounds like there's not much interchange with later model stuff.

 

per the HOLLANDER mine goes back to mid fiftys to about 72

 

If your goes back to '65 you should be covered...same PS box for '63-'65...

 

not according to my hollander

 

actually later boxes DO interchange. i don't know specific years, but "later 60s" buicks at least, have a similar box that mounts with 4 bolts instead of three, but otherwise is a direct swap, you just don't use the fourth hole*. i did the swap several years ago so i don't remember what the donor was, but it was some late 60's buick full size car.

* the fourth hole hangs below the frame. if you can it would not be a bad idea to fab up a bracket and use it.
