no, they wouldn't fit over the hub before on a 1.25" rotor. Now they do but the dust cap still is an issue.

Here's the pictures from his thread 18X8's

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5

So would the cap fit with a small spacer and these would bolt right up? Any pics?

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5

Can you flatten the bearing dust cap and make them work?
Maybe remove the dust cap and see if they will bolt on.

Just curious,... how wide are your front rotors?
1" or 1.25"???

You got the old design,... the same that I have.

I plan to cut off the end of the spindle and modify the dust cap.
They will bolt on the 1" rotors. Always did.

New design isn't out yet,... just like "Hickup Pickup" said.

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5

measured this morning and they are 1 1/4 rotors........ I have decided to return them though I will just run some coys or something....... will get some pics before returning them though. ..... either my rotor is different or the wheels have changed...... I don't know but what I do know is they slide on but u cant not snap on the center cap.

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5

My 18x8 test (black) test wheel that I bought fits on my 1997 Tahoe. I'm having the spindles changed soon from BT to DJM. I may have some machining done as I really want to run the 3-spoke knock offs as well.

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5

I thought I would post my latest update from my "original design" wheel thread.
Got my new zinc plated 1" wide rotors from SSBC.

Like I have been saying,... these 1" rotors are the answer to all the Boss 338 wheel fitment problems.
(Until the new design comes out)

Here's how much MORE the hub is recessed into the wheel which allows the cap to fit with no mods.
No machine work, no glued on cap.
The only thing I didn't try was a bearing dust cap.
But I think this is the only answer to use the old design wheel without any machine work.

The last two pics are of the cap installed and the wheel setting on the stock unmodified rotor.

So,... if you need:

1) drop spindles
2) new rotors
3) new calipers

Just buy the 1" wide stuff and you are good to go.

Drop spindles for 1" rotors are only sold in 73-87 (balljoint) versions.
So you 63-72 guys will need to change ball joints and tie rod ends.
(all of the above parts,... I needed to purchase anyway)

Keith, what are those going on, 69? They sure are nice looking.
I'll get a set when the new design comes out.
There you go Boss, one more person interested in fitting 11/4 rotors.

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5

Hey guys, I am new to this website. I read this entire post before I ordered my Boss 338's and decided to go ahead and give it a shot. I ordered the 18x8's for the front and 18x9.5's for the rear. Anyways, I put them on this morning and had very little fitment issues. I don't know if I have the light duty rotors or not but the only modifications I had to do was hammer in the dust caps and cut off about an 1/8th of an inch from the center cap clips on the front wheels. It was simple and I am very pleased with the results. I still need to do a drop on my truck so that the front doesn't look so odd but that will be coming soon. Here are a few pictures with the new wheels installed. FYI, I don't know if anyone else has talked to Steve at Mrwheeldeal.com but that is where I got my wheels and tires. He had great correspondence and great pricing as well.

Ronm909... if we can, please keep the items for sale in the parts board if at all possible. And according to the rules, sales through pm's aren't allowed.

And I'm sorry to hear they wouldn't respond to you concerning the shipment of the wrong wheels; that's crazy!!! Nice looking setup on the frame though.

Out of cusiousity, what are the specs on the tires?

It'd be nice to know which company this was so others could avoid them.

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5

OK sorry about that. Company is Wheels next. first they took my money and sat on it for a month while wheels were on back order, but it was a different rim, finaly I was able to get these 338s at a "discount", but he sent me all 10"s.. as for the tires... I dont know if these tires will work but I got 3 used 315/35 20 with about 50% tread for $100 on craigslist. figured I try them out, if not at least to have a rolling chassis for now.
