What offset? I have a set from my MGB (I am running 15 inch wheels), but the offset may be too much as I have flares. I can measure and take some better pictures (see the attached). The Goodyears were long ago dismounted, and the wheels are now cleaner, though not yet polished, etc.
Just trying to help: the 114.3 size was curious. It's millimeters. 114.3/25.4 mm/inch = 4.50 inch. That's the original British dimension. Don't ask what it is in angstroms, hands, chains, furlongs, light-years or parsecs - I could but I won't. Joel
I think he is looking for 14"wheels, not 15's. Try looking for some mid 70's Toyota Celica aftermarket aluminum wheels. I had a set on my TVR but they went with the car years ago. I have lots of 13's and 15's but no 14's. Sorry.
