Does anyone know if the Boyd Coddington Smoothie II comes in a size that will fit my '73? If not can I "make" it fit using spacers and whatnot? Is that a bad idea? Should I just stick with seomthing that will fit?

Sorry for the flurry of questions and THANKS!!!!

:thumbs:

Here's a pic of it:

 

Those look ALOT lke the Edelbrock 409's and if i'm not mistaken someone here has the 409's so if you can't seem to get an answer on the Boyd's maybe the 409's could be an alternate.
Good luck and hopefully someone with more knowledge on this will chime in soon.

 

Size isn't the only consideration determining fit. The shape of the inside of the spokes and backspacing come into play. The only way to know for sure would be to mount them on your hub. Corvette calipers are larger than most and the spokes need to clear them. Those though, look like the spokes are curved enough to clear the calipers. But only a test fit will tell, or maybe the manufacturer can tell. :thumbs:

 

I am ordering the 17X10 for my 77 with 4” back spacing. I emailed the company I plan to order them from and they stated that the wheels would fit but would stick out to far. I putting on fender flairs, so that’s what I want. They suggested getting the 17X8 with 4 to 4.5 backing spacing. Have you done any pricing?

 

I am thinking about the 17x8 wheels.

Actually the reason I am considering them is because they had them at Discount Tire for $208 (the 17x8). I thought for Boyds that was VERY reasonable.

Thanks for the info on the fitment guys! :thumbs:

 

That is a good price. I was quoted 995 for the 17X10 and 130 for shipping. Here is the email I received for the company.

The wheels are custom made to order, so there are no returns prvided the wheels are made properly to spec as ordered. I can tell you on a '77 Corvette with stock calipers, the wheels fit just fine, and have no problem clearing the calipers. Bolt pattern and offset are all specified when you order, so it's not like you'll get something that doesn't fit because of those things.



The 17x10 will stick out, I recommend a 17x8 with 4" to 4.5" backspace.

 

TT II's with 4" backspacing 17x8 will fit with no mods.

 

IF you look at what a factory stock offset is, you can figger the wheel centerline, simple really concept wise.....frankly in any HUB arrangement, be it a C3-C4 whatever, those rear hubs are called that because the inner and outer bearings are so close together, creating little spacing for 'leverage' on the wheel/tire combo....so typicically designers can have some offset, but I sure as hell would not play with what the factory allowed.....SO with STOCK t-arms you will see that silly ebrake tab is limiting in increase in allowed width to the inside....I moved mine to the inside of the rotor, and moved the cable shroud clip to the ourside on the frame end...to compensate, keeping the stock ebrake assy....
NOW, the thing I noticed was the increase TO ME was only about 3/4 inch...perfect for ME, as I wanted to use later C4 vette wheels....9.5 inches vs 8 inches....so for those wheels I wound up with a 2.5 inch thich adaptor....
now any other wheel fittment assuming you go along with my 9.5-10 inch max width....would be wheel design...no comment from this Indian....

so the situtation is IN FACT I do not know what if any further increases in overall wheel width are possible IF using the aftermarket offset trailing arm assys.....they may buy you another inch or so...maybe not...

I still like NOT altering the wheel centerline to keep bearing loading centered the way the factory guys liked.....engineers first law.....'thou shalt NOT stress the merchandise".....since we disobey this law in many other respects, maybe some of the 'laws' need adhearing to...lest we invite the devil......

It's a bargain price for these wheels. Well worth asking the tire place to fit one to your car to see if it will fit...they'll do it if they want to sell them. Don't take their word for it though, check the clearances yourself and use your stock lug nuts to make sure you get enough turns past the end of the nut.

I've owned a set of these for 2.5 years, but fitted to a late model Aussie GM car (check my URL for pics on the '95 Calais). I was going to sell them, but on a whim I put one on the Vette "to see how they'd look". WOW!

My wheels weren't manufactured for Chev, so they're not a perfect fit; hits the caliper and lower control arm. Looks like I'll need a 1" spacer/adapter.

From what I've read on this forum, spacers and adapters are safe, but since you're buying new wheels, I would try to buy the correct offset/backspacing before you commit to the spacer/adapter. I'm certain that BOYD would offer the correct wheel for Vette or Chev.

Good luck
