Predator 10k help, advise needed

Ok so I did some tinkering and (jimmy rigging as some say and here's what I did. I had my Wilson with 10in shaft and had a old Wilson 5k with 10 in shaft on truck on top of the hose rack where it didn't ground and was just a wee bit too tall. Then I went over to some wrecked trucks here at Schneider location cause u all know they will tear some trucks up these professional drivers they are lol.. I found another Wilson 2k with 5in shaft. I then put them all together knowing it will still be too short, I did this cause I'm bored and not sitting in that tv room hearing them cry and wine bout stuff like they love to do. Well I still need a few more inches, so maybe the 22in shaft off eBay with The 5in added on might be perfect Idk, I need look or measure better I think. I do like what I have rte now though, I got my swrs down even better. I'm at a 1.1 on channel 1, 1.1 on channel 40 and it's almost 1.0 on channel 20, just a smudge off from being 1.0.. this is on a freight shaker also so that's pretty good swr readings. I'm just Useing my lil astatic meter though , the one in radio shows all swr 1.0 needle doesn't move they are so low

 

I guess my swr is a lil bit higher on channel 1 than 40 but it's getting so close I'm not sure I should fool with it anymore especially since I'm climbing on top of hose rack to play with it everytime

 

If I knew the predator 27in shaft would work for Wilson that would be awesome. Order it and done
