SBC waterpump measurement

guys,
does anyone know the measurement difference between a short and long water pump ?
im running a 1980 350 out of a truck with long water pump, alternator on p***engers side, and got some late 60's SBC alternator brackets to switch the alternator to the drivers side, but those motors use a short water pump. i need to make a spacer to make up the difference and want it to be exact.
thanks

uhhh....get the right pulleys, change the pump, do it right.

 

lord whats a chevy water pump cost 20$.........................literally

 

perfect, thanks a bunch.... thats what i needed.

 

i already have a new water pump and dont want to buy a short one. and dont want to buy new pulleys. got alternator brackets for 20 bucks. it was the easiest way for me

 

I just paid $34 for mine, but I got the new, not reman.

 

Yea, I paid more for my pulleys than for my water pump. And I had to get the ****py chinese **** cause all the originals were stupid expensive!

 

yep, exactly.... thanks

 

Lenord,I think theres some long pump **** under other **** under my bench,come on by and we'll dig it out.

 

thanks much dana... im fabbing and modifying up some brackets now ans hopefully will have it whipped. if i do need more stuff, i surely will give you a shout.
