No Bling Bling?

It's looking like a good straight clean install..... Just a minor suggestion from the peanut gallery..... On the step on surfaces polished stainless steel diamond plate. On all sides and bilge 1 mm mirror polished stainless steel. It makes wiping up messes real easy and sets every thing off.

Picky, picky, picky.... BUT, good suggestions... We've basically got 2 weeks to complete a "normal" 8 week build cycle....

The drives are 1.35 but what are those boxes on the back of the engines are they a tranny or crash box? If so is there a ratio in there?
