PAS Swap

[Reaper]

I have a 1972 R/R that I am about to bobtail, I also have a 1989 R/R that I am stripping for spares, Can I swap the pas box off the 89 into the 72, is it just a bolt in job or do I need to get a bit creative?
Yes I am being lazy asking rather than measuring it up myself!

The main thing to check is the number of bolts on the top cover of the box.

There are essentially 3 types...  3 bolt, 4 bolt and 6 bolt.

The majority of vehicles now have 4 bolt boxes on them.    These are not interchangeable with the 3 bolt type as they have different hose fittings.  I would guess your 72 has a 3 bolt, and the 89 has a 4 bolt.

The 6 bolt boxes should be OK to swap with the 4 bolt.

Thanks Tim,  I seem to have left out an important bit of info, the 72 rangie is manual steering at the mo  OOOPS!  and I want to convert it to PAS using the 89 box & pump etc?

[Bobtail]

the whole kit should just bolt straight on
are the engines the same ie v8
so the pump bracket will fit as well :D

[Reaper]

That was the answer I was hoping for and yes they are both v8's.

[Bobtail]

only problems if you mix early three bolt box's
which are imperial thread and later four bolt
which are metric thread so pipe work does
not mix and match

good luck :D

Err hang on, aren't the front timing case covers slightly different also? so you may have to fit the 89 engine too.

Ive got a 3 bolt PAS but I use the 89 pump because of the timing case.

That was the easiest way for me to get round it.  :D
