Engine Swap, A/C question

[Gorilla]

03 silverado originally a 4.3 6 cylinder engine with 4l60e trans. It has been swapped to a 5.3 LM7 Engine and 4l80e trans.

 

My condenser,  discharge line (high pressure) hose with switch, orifice tube and accumulator all need to be replaced. 

Ive been comparing some part numbers on rock auto and it seems the condenser and orifice tube are the same GM part numbers between the 4.3 & 5.3

 

As for the Accumulator there is no GM part # for the 5.3 and all aftermarket accumulator #'s seem to differ on between the 4.3 & 5.3. 

Running into the same problem with the discharge line too. All opposite numbers. 

 

Anyone that has done a swap can you please advise what accumulator and discharge line with switch that you have used? I could also use a part # for the switch on the discharge line  & if there is a seal kit available unless all seals come with the new parts?

Since the body is the same, and engine different, go with the 5.3 option. Block sizes are different so the pipes mounted on or around are different.

Much thanks for the info. So just run new lines for a 5.3 and get the accumulator for a 5.3 and I should be good then? Anything else needed?

Would you know what the part # is for the switch on the discharge line?
