Need help installing a CA metal body and front end on a TM mp5 sd6

[Mobius49]

I may have missed instructions already on this site, and if so I apologize, but I couldn't seem to find any. Just wondering if anyone has a url or other source for instructions to install this stuff. I'm fairly new to airsoft, and I've dissasembled/reassembled my pre-upgraded mp5 with no problems. (I went to http://www.mechbox.com/site/upgrades...bly-video.html ). The CA body actually comes with a different type of hop-up adjustment that is hidden behind the ejection port, rather than the lever on the fore grip. This makes the cocking lever actually FUNCTIONAL which is cool! The problem is that when I install it, I can't seem to figure out how to spring-load the cocking lever. by default TM mp5 cocking lever is spring-loaded (though it's just for show), but when I use the new hop up the lever only has spring resistance once it's pulled most of the way back to open the ejection port. Otherwise it just slides loosely, (which bugs me). I'm probably just missing some simple step, but any info on this would be great, thanks!

Weird....
Without ever having seen either body...
It sounds like the anchor point for the spring is further (back??) on the CA body than it is on the TM body.
Please let me know if this helps... (now I'm curious! 8-) )
