1994 MAZDA MX-3 GS 1.8L V6 5-Speed Please Help Me Fix Him Up on 1994 Mazda MX-3

Current Problems:

1) Can NOT Shift Into 3rd Gear While Driving (Makes Very Audible Grinding Sound & Will NOT Stay In Gear (Slips Out). It Will Go Into 3rd Gear If Standing Still & It Will Pull Forward In 3rd Gear From Dead Stop. I'm Not Sure If I Can Use The Shift Linkage Rods From A Used Car (See: Below FYI Info) Or Maybe It's Transmission???

2) There Is An Electrical By-Pass Placed On The Light Switch...So When I Turn The Headlights On...They ALL Come On No Matter What Position The Switch Is Set To...So I Can't Just Use My Park Lights. I've Considered Replacing The Steering Column Or The Dimmer Switch Assembly?

3) All (4) Struts Are Rusted, Broken (Found A Broken Piece Of One Spring On The Ground) & Need To Be Replaced. I've Been Researching 'Quick Struts' But I Don't Think They're Available For My Car's Year? Really Confused About What I Need To Completely Overhaul? Any Particular Brand? Where's The Best Place To Have It Repaired?

4) I'm Losing Oil Somewhere, Not Seeing It On The Ground...But It's Going Somewhere (I Believe It's The Rear Manifold Or Head Gasket Maybe???) I Use Havoline 20/50 & Add Lucas Oil Stop Leak Once A Month.

5) Considering Replacing The Radiator (Mainly Because It's Slightly Bent & The Color Of The Fluid Appears So Dark) Or Maybe It Just Needs A Major Flush (Which I've Done But It Still Appears Rusty Colored To Me)? I'm Presently Using Preston Anti-Freeze. I'm In Fluctuating Weather Being From Midwest But Go In & Out Of Warm Climates As A Truck Driver.

6) Would Like To Replace The Front Bumper, Repair Passenger Side Fender & Replace Tire Well Covers & Have Other Body Work Done In Time?

**FYI: There's A 1994 Mazda MX-3 Manual Transmission @ Pull-A-Part Right Now...For Parts???

Anywho! That's Just Some Of The Fun Stuff I'm Working On?!

Struts Are The Immediate Issue To Me?!

Thanks For Your Help!
