Were you thinking of having the oil pan off when you are putting it in? They must be bent and put in position so not to hit the crank.. Many guys instead of using stock type tubes , make there own. They get a fitting that is 1/4" pipe to 3/8" tubing. Then after taking out the old tube , tap the hole with a 1/4" pipe tap. now just get a piece of 3/8 " steel tubing and cut and position to fit .. This is what I did after not getting a new tube to fit and damaged it .
