I have a firehammer clone and fg. the clone chassis is a tad longer than the fg. and on my fh the front bulkheads aren't the same. it'll line up if you also use the smaller front bulkhead. I don't understand why the clones did it. on my on road chassis that is flat, the front part of the bulkhead is taller and leans to make up for the lack of chassis kick up... the bend. on the fg off road, both front and rear (a and b) of the front bulkheads are the same height. the clone has on road bulkheads so even more kick up. this leans the front back...
I am swapping parts around between 4 chassis, 2 clones and 2 fg. 2 on road and 2 off road...
also take a look in the sale area page 2 at sickboy's fibreglass bodies. trying to decide on which one(s) I want still myself
