Dale,
Got somewhat the same e-mail reply. My gun was not apart to measure at that time, so I ordered the "New-Bam,Gamo,TX, Problem Solver Seal set. It's two slightly differant sized seals for Gamo's. His reciept code is, " TeslaApexS".
The kit came with a black and a red seal.
Once I got the gun open again, I miked the bore and it came up .983. The black seal being the smaller OD of the two was the closest to the OD of the original seal that was in my .22 Whisper.
The lube kit is LP-66Y.
Since I had installed an Air Ventri gas ram and the original spring looked ok for a back-up, I didn't get a new spring, so I can't help with that number. Maybe a PM to Bob (CDT), or Gene to see if they know which spring to order for a Whisper

??
Paul.
