I live in the Huntsville area now...but I am familiar with Houston as I own a home southwest of Houston about 30 miles in Rosenberg. My car is AWFUL in the rain, those huge back tires cause the back end to float and brakes that lock up easy will make it even worse. The valve gets ordered tomorrow and soon as it arrives I'll go out to the "rod shop" outside of town and have it installed as you and MickMate have recommended...without it I can see the writing on the wall! He says he has the tools to do the install and I don't want to invest in a double-flare set.....yet, that is!
Cheers!
Dugly
