pushrod question?

Some advise that you're not going to like to hear......Don't start the project until you're sure you've got all of the parts or funds to complete it. You wouldn't be the first to do it, but starting off that way usually ends up costing you twice as much in the end. Put it on hold, start saving up now and pick up where you left off when you can afford it. Going at it half a$$ is only going to leave you frustrated and broke.
