A little grinding is right up my alley- I have nice big compressor and die  
grinder I do heads with that will work quite nicely. 
As I already have the other pump (almost brand new) it is really not a big  
deal to do a little modification.
That was exactly the answer I was looking for. 
So, a BIG thanks!

The V8 PS pump is model specific.  5K, 100, 200 pumps won't fit into  the V8 
PS pump bracket because they have a slightly different shape to the  casting 
and it won't clear the bracket.  Otherwise, the mounting bolt  holes are the 
same.  I remember thinking, after I'd used my last seal kit  on a 200 pump to 
put it into my leaking V8, that a little grinding on the  casting would allow it 
to fit, but I opted to wait till I could get more seals  to redo the V8 pump.

Hey  all,
Has anyone ever replaced their hydraulic pump on a V8 with one from  an 
earlier model, say perhaps from a 86 5000TQ?
I know in principle  the pumps work exactly the same, but are the mounting 
holes and bango  bolts the same size? 
I would not bother me if the location of the hose  inlets and outlets are not 
exactly the same. As long as the mounting  holes line up to the brackets to 
the block. Initial eyeballing of pics  of new ones seem that they are the 
Can anyone confirm?
I have a  pump from a 86 TQ that was rear-ended in storage, and I not too 
sure I  want to go make the trek and dig through 50 containers to see if I 
find it if it is not going to work.
Thanks in  advance,
