can this wheels fit my stock el-camino??

18X8 UP FRONT AND 18X10 ON BACK The front tire size is 225/40/r18 and the rear is 245/40/r18

THE BOLD PATTERN IS 4.75, AND THE FRONT WHEEL SPACING IS 4 1/2 AND THE REAR IS 5 1/2.I

please help me

I'm measuring for a simular set up. I'm looking at 18X10 5.75 BS and 18X8 either 5.5 or 5.75 BS for 71 Chevelle.
They should fit yours, but YOU'LL NEVER KNOW FOR SURE on your vehicle unless you measure. With that said, because my differential is 1/2" FARTHER over on the pass. side than Drivers side, I have to order 6.0 back spacing and maybe use a spacer on drivers side. Don't need to tho as there would be 1/2" from inner wheel well to tire on my set up.
My 1/4s have been changed at some time which probably is why the differents in rear wheel well.
ALSO, that tire on the 18X10 is too small for that 10" wheel.
So if your car is straight as an arrow those wheels should work.

thanks

Andre, Will send you pics as you requested when I get back,my JYD are 18/8 18/10 with 245/45zr18 27540zr18

ok thanks il waith:)

Made mistake on saying 5.5 and 5.75 on front wheel BS. I meant 4.5 and 4.75.
I went with the 4.5 for the 18X10 front.
