back when i worked at the muffler shop i know they would eat donut gaskets easy
there was 4 or 5 of them used on the post office route, never said anything bad about them from what i remember
years ago one of the wifes kids got dog bit.
after going to the hospital, went to the guys house (police put the dog down) i ask the guy
to pay for our hospital bill !
well he did not pay so lawyer i go, got a judgment on the dude and 4 years later
he had to pay 5 times what i was asking for in...
a little practice goes a long way
from welding like you would any other time, for me just turn the heat down a click and jump in there
but then again i was self taught in 1978 at a muffler shop so overhead welding was what we did
turn your heat down and try short welds like 1/2 inch long
do you have a stick welder ? i have welded 3 different tranny pans under dozers before with a pipeliner
only had to drain one and touch it up !
