Rusted rear diff cover, help!

Hi everyone, apologies if this was covered but I'm on my phone and pressed for time. Any quick solutions aside from covering the rusty plate with seal all. Heard that they make a cover that can be welded on after the original is grinded off. Thanks in advance!

 

Barnes 4wd makes a replacement cover to weld in place after the original cover is cut off.

For a 2002 model, it looks like this will work; http://www.barnes4wd.com/Toyota-T10...ndra-Heavy-Duty-Differential-Cover_p_359.html

 

Andy, thanks so much for the information and sorry it took so long to thank you! I'm crossing my fingers to get thru the winter and deal with it in the spring! Covered the diff with seal all, looks good so far!
