Can anyone recommend a mechanic in the Houston, TX area that can work on a Conquest?

Hey I'm looking for a Power Steering Reservoir for my 87 starion, it didn't come with the car and am having troubles locating one. Has anyone used one from another car like the montero or do you know of one that would work?

Pull a Part Knoxville, TN as a 88 and an 89 conquests. both red with black leather interior. Seats and interior are in ok shape. sorry no wheels at all. 3 of the 4 front fenders are bunged up. Hate to see them go to waste. The 89 still has the motor. Its an automatic.   Hope to get some parts tomorrow. (tues 29 oct)

So, will a 6 bolt axle fit in a 87 diff??? or do I need an 88/89 diff to go with these 6 bolts?? Thanks
