(I posted this in the early a body forum before I realized there was a dedicated brake forum-sorry mods)

I will be converting my front drum brakes to Wilwoods front disc brake conversion for my 64 Valiant. I was all set to purchase the 9in kit. I was told it had the original drums.

Did 64's only come in 9 inch drums?

However, when I measured the studs I discovered I have large bolt pattern.

I wasn't sure how the car could have LBP on 9 in drums so when I removed the wheel I saw this....

Looks like they re-drilled the brake drums and put the long studs. Not sure
how common that is to do. I have seen the rear axles being drilled through but not fronts. Anyone else seen this?

So now I am not sure if I have 9 or 10 inch drums and spindles. Is there way to easily tell what size these are? I need to order the brake kit this week and don't want to order the wrong kit.

I measured the back of the drum at 10 inches.

Is the only way to tell for sure to take the drum off and measure the inside diameter to know if it is 9" or 10"?

Thanks in advance for your help.

( wheels are 15 in Weld Racing)

pic of car is this matters...

Thank you! What I am looking for in the bearings? Sorry I am new at all this.

They could be 9" but looking at your tape it is really hard to tell for sure. You are looking for the bearing ID because that is what is important on your 9" kit. Look at what is stamped on the face of the drum as I told you in a pm.
 
why wouldn't you get (73-75) Disc spindles? much more Heavy-Duty, and you could go up to a 11.75 rotor?(you'd need the UCA also) just curious.

It might be the fact maybe there isn't a ton of good used parts to be had in Canada where he is and shipping everything from the states would really be expensive.

If the parts are available I would swap everything over to factory parts and forget aftermarket parts.

That is actually a good suggestion. I am told the 73-75 pushes the wheel out about 1inch that would actually help me as the wheels do rub the fenderwell headers. I would just have to make sure I have enough room.

So put on 73-75 spindles then throw on the Wilwoods?

What other parts of the 73-75 upper brake system would I need to do this? Upper control arms etc?
