Went to do a fluid change on my F250 and the fill plug was seized solid on my sterling diff. Searched everywhere for cover with a fill plug to change to. TMR was the cheapest by $2-300 and Canadian. This did not show in quality of the product at all. The welds were clean and sturdy. Welded inside and out. Came with stainless mounting hardware, when others didn't. Only thing is you have to paint it as it came in bare metal with a slight bit of oil coating. Not a problem in my eyes as I am addicted to painting everything. I think I will pick up a front for my 60 next fluid change!
Keep up the good work guys!
