You're talking about the "compress it and get the snap ring off so you can transfer it to the new piston set" spring that this overly trained GM tech never saw in the instructions 'til I did my 2nd conversion so I had to redo the Denali.....I think....

The piston swap is easy (much more easierest on the Blazer than the GMC due to "jaust pipe crap") but the fact OPT's instructions don't mention the captured spring P I S S my off.
