a little progress
 

Kinda sorry progress but it all counts.Tanks mounted.Wait on another compressor and a couple of other things to arrive and start shoehorning them in under here too.
Oh cut out the old rear crossmember to make room for the fuel cell and fabbed up this new bolt in xmember.

I like the tank idea.. how many gallons ? but wheres the exhaust going to run ?

thanks camaro thunder.They're a bit over 8 gals combined by my figuring.The exhaust is going to have to come off the manifolds and duck under the frame just before it levels out and follow the outside of the frame to the back.Not exactly ideal,but it's necessary.My exhaust guy says he can keep it neat and hidden without too much trouble.
