Brake line size (ABS to rear brake hard line)??

Hi all,
Wondering if anyone knows the hard brake line size for the line starting at the ABS unit going to the rear brakes(2 lines). The JERKS that cut off my catalytic converters cut BOTH of those lines right under the passenger front seat before the union leading to the back brakes. I called the local dealership and they gave me the part numbers for the new lines, but I just don't know if you can 'snake' the complete line in, so I'm thinking I might have to just repair the line (hence the need for the size) the part numbers provided are 47322-0C110 and 47323-0C090. The lines aren't terrible cost-wise ($57.46/$55.11 respectively), but I'm just not sure you can put them in with the engine and all accessories in place.
I've read through all the hard-line threads, but they all refer to the small hard lines by the front calipers and just not sure if they are the same size (3/16th)....And I DID ask the parts guy at Toyota and he did not know the size and said he didn't know how to find it out
Thanks for any help!

Hi timesinfinity,
Yes! I replaced with OEM lines. It wasn't "easy" to snake the LONG OEM lines back, but I did it. If you have to do the same, just take your time, do one line at a time, and mark your spots. I probably broke just a couple of the oem retainer clips on the truck, but looking at it if you didn't know I had done it, you sure couldn't tell by looking. Let me know if you have any additional questions. I'll be glad to TRY and help!

 

thank you! this is great info!
