This was combined on the title. When trying to find a core....I kept coming up with a smaller one then came out of the truck(6.1/2 x 2.1/2 x 7.1/8. I do have an outside air door that vents to the firwall wiper area. Fresh air intake. My core is 2.5 thick,6.5 tall and 9.25 long. This is what came in a c-20. Im wondering if my cab was off of a c-20 or has anyone else seen this larger core in a c-10? Thanks Grinder4400 | | | | | Joined: Sep 2003 Posts: 2,384 Shop Shark | | Shop Shark Joined: Sep 2003 Posts: 2,384 | the deluxe fresh air heater has the bigger core | | |
