Scarebird Conversions

[Bullzak_83]

Has anyone used Scarebird.com for brake conversions. Custom10nut told me about them, and they are differently cheaper then going full conversion., The question I have is my 70 cst/10 has a 6x5.5 x 1/2" lug bolt pattern, in the kit from scarebird the rotors you use is from a 1995-98 3/4 Gm, to get the 6x5.5 pattern. My son who happens to work a a parts store picked up a pair of the rotors, but they use what has to be a 7/16 lug.

I am checking on the rotors to make sure they are correct, but if they are, does this mean I have to change out the rear lugs to 7/16" I have email the site and waiting on a response, just curious if anyone has installed this kit and what was the results.

Thanks.

I think you have the lugnut sizes swapped
All 67 72s I have had 6 bolt where 7/16 and 5 bolt trucks have 1/2 lugnuts

Did you upsize your wheel studs on your truck in the past ?

Gmc684x4, Nope I bought the truck back in H.S. and I have never done anything to the brakes other than change pads back in the day. Now that doesn't mean something was done before i bought it. That is why I'm confused on the lug size, but the truck differently has 1/2 x20 lugs.

The rear lug studs on your 70 c10 should already be 7/16”.
The 95-98 rotors should be metric.

I used this kit on the wife's truck. The front studs are 14mm

67 Twins, are you running 17's for the wheels, that is what my son just bought, and they are sitting in the box at this point because once I mount tires,on them I own them.

Yes as a matter of fact I am. 17 inch Vision 55 Raylle wheel is what we are running on that truck

Hey Lolife99, Everything around the truck is 1/2". Up to this point I have never thought about the lug nuts on the beast. But I am now!!!

I had found this lug size on the web,and down under Chevy/Gmc Trucks I found the Pickup (6-Lug) 37-87 1/2" x 20

That just shows a great example that just because the information is in a table
format doesn’t mean it’s accurate

8 lugs back in the 1960’s definitely were NOT metric

x2.

[lolife99]

That’s incorrect

[lolife99]

Correct sizes,...

That is incorrect as well.

For 8x6.5 bolt patterns:
thru 1970 is 1/2"
1971 and 72 are 9/16"

Yeah, I thought so.

Sorry about that.
I learned something today.

Same ole disc brake related updates.

Hey Group, to everyone that replied to my post. I apologize looks like I need to go back to school for a little refresher in FRACTIONS. Gmc684X4 wins the prize, yes I had the sizes swapped, I do indeed have 7/16" not 1/2"
And 67 Twins you were correct as well.
With that being said and after a little correspondence with Mark at Scarebird, he recommended changing out to metric Lugs on my new 98 gmc rotors to 1/2"x 20
Which I plan on doing.
My next question is it possible to find a 1/2x20 lug in which I could install in the back to replace the 7/16" x20's without having to do a bunch of re-drilling on my drums.

Thanks again for everyone's feedback, I'm a little rusty on working on the ole truck, but it's coming back day by day..

Everyone have a good Thanksgiving, and thanks again.

thank you

Apologies for raising the dead, but not much else on the boards about this vendor. Looks like you have been running their kit for almost a year. What are your thoughts thus far? I am thinking of going this way for an old beat up long bed.

Any tips, or other parts needed I may unawares of?
