Can anyone post a pic showing the difference in brackets for wood firewalls and metal firewalls? My '21 has a wood firewall but I believe the brackets I have are for a metal firewall. Also I need to see a photo of the inside, where the bracket bolts come thru, under the floorboards. Thanks very much.
Tommy, this should answer your question.
Easy to wood firewall had round holes for the firewall carriage bolts steel had square
I might have an extra pair
