So I came across a reconditioned AC and Heater box from The Part Guy: thepartguy.com and got a good deal. I have enough parts, but they would have to be mailed off and then reconditioned, so I ended up getting the pair since they were available and ready to go – along with a deal for buying both at the same time!
The problem is – I don’t know where I have room to store these until I mount them… But since the firewall is painted, there is no reason why I can’t go ahead and mount them! I need to order the proper screws\bolts and the sealant used for these and then get them mounted to the firewall! Give me a few weeks and I should be able to post an update and pics!
