I feel your pain, have had many a day like that...just have to take your time and not rush...I have freaked out on an install before and the water and oil lines just wouldnt line up and seat...spent like 2 hours fucking with the hard lines...got kicked out of the hobby shop since it was closing...came back the next morning and they plugged right up in 5 minutes....just was frustrated and rushing the night before...cheers and have a beer brother and thing of the money you are saving turning your wrenches yourself
