I'm looking for some nice wheels for my 79 monte carlo project.

Found the BOSS 338 rims:

Will these fit on my 79 Monte Carlo?

18 x 8 Front wheels
Offset: +2mm, Backspace: 4 1/2"

18 x 9.5" Rear wheels
Offset: -4mm, Backspace: 5"

thx guys!

you will need some spacers but it looks close to dead on in the rear... are you running discs or drums in the rear?? .. but yea they will fit.. i have 8.5 & 9.5X18 forgelines on my 79 malibu, and thats without notching the frame.. AND the bu wheelhousings are smaller...

hmm okay. still stock drums but also thinking about discs - the car's still under progress

well then i would definately go for a wheel that required a spacer.. the disc is thicker than the drum and will space the wheel out about 1/4 inch when you swap from drum to disc... and it is ALOT easier swaping to a thinner spacer than trying to roll fenderlips, experimenting with narrower tires or having material mashined from the mounting flange...

and it looks as a heck of a deal on a great looking wheel

Could you get away with a 10 in wide rim in the rear?On a 81 bu?
