Slightly confused as to the array of part numbers used on these.
Im after a straight forward swap possibly with the intention of just swapping the electronics bit in situ.
BBa have a list of part numbers,
http://www.bba-reman.com/content.aspx?content=cadillac%20_bosch_5.3_abs0 265 220 427 is mine.
This is the only number i can see with the unit still in situ.
This number is on the aluminum pump block.
These are not the only numbers quoted on egay. You also have ecu numbers quoted and for example DX and DY numbers.
Is a number match on the alley block enough for a straight swap?
