You might be interested to know that Frigidaire had the 72" coils in stock. I was pleased with that. $21 each. Very good customer service.

I have a 1983 300SD. I'm concerned about coolant hose routing and being able to get to the top of the tank. I may have to leave out the rear deck trays. Do you have any pictures of the tank in place with coolant hoses run?

When you cut out the holes did you worry about metal shavings? Golden Fuels (Greasel) recommended using slight grind followed up by a metal chisel. Any thoughts? Did you wipe inside clean after grinding?

In hindsight, is there any reason to go with brazing over JB Weld? I had the tank cleaned by a radiator shop and they can do the brazing for me.

Also, upon reflection, any need for being able to keep the cover removable as an inspection whole?

I think I'm going to make sure there is a gap between wraps so it flows through but acts like a baffle.

I appreciate your thorough details. I'll let you know how my project goes, if you're interested.
