I have built some cars with motorplate
I both cut my own plate and bought
plates but i dont remember where i bought
them.
I prefere to use front plate and mid plate
but i have used front plate and trans mount
but then its important to use a rubber mount on the
trans. If you mount the trans solid it will crack the
trans if the chassie is flexing
Water pump bolts are enough, A Topfuel Engine
is mounted to the chassie with 4 hoseclamps
Its Dragracing chassies i have built so i dont know
what works in roadracing thats your car is built for
if i have understad things right
