I think I may do some shopping for a 34". Reason is at this time I will be running my trans fluid through it, and the extra 6" would help will be good. I am also thinking shipping to 98373 will be spendy. I will check on local prices. Thanks.

Actually the 28" might be my choice as I am going to duct in a dual air intake, running from each side of the radiator though K&N panel filters one on each side.

Just ran out and measured the support opening and it is 28.50 wide. So the extra 6.00 would catch no flow anyway.
