"is it heavier?"
It is MUCH heavier than original! But it looks million times better than it never would...
"and is that pan gonna take a hit or even a hard scrape"
It is made of the same alloy than this "aluminium man" makes race car wheels! And walls are at least 1/4 "!
This professional (retired) "aluminum man", who lives close to me, has done almost everything that can be made of aluminium... I asked if he could cast some gasser wheels or AMC blower intake... No problem! Only if I can fabricate a suitable pattern for him... I have known him over 25 years, but never before asked him to do something for me and my projects! What a fool I´ve been! Have to go to my garage and hit my head with sledgehammer!! Twice!!
