thanks! now, that said...
MAKEUP!
Anybody remember the Daffy Duck cartoon where he kept getting his face blown off and would walk "off set" and scream MAKEUP?
Well, I am a little bit there. The 18" shock was just going to bind at full extension and that was not going to be a huge issue as it was just a little clearance grinding to solve. However tonight I got in there and got the base of it held into place and started to run the shock through motion into compression... well... I knew I lost 1" of compression asking for an extended eyelet at the one end which indeed minimized the binding as I had hoped. However, what I didn't realize is that I was going to lose another 1.5" with the extended spring cup - the shock body bottoms out on it! It all makes perfect sense since they have to be the same size to fit the spring, but not something that crossed my mind and was apparently a non-issue on the Porsche as I had the exact same setup on it.
I took a shock with 6.2" of motion down to a measured 3.8" and it bottoms out at about 1/2" of bump
So I will need to knock the mount tabs off and flip them over to move the rockers over the support, not under. Not a big deal really, just one of those things. What it does mean is the tubing I have cut and tapped for drop links to the suspension and could be used for the sway bars now all need to get longer as I have to fit a shock at least 3" longer to get full travel back.
Hopefully that is all I need to do; I need to really look at it again tomorrow and think it through some more and try to make sure I am not missing anything else
