What brake lines for drum to disc?
Just got my moser rear set up for lt1 discs, and I'm not sure which brake lines to buy. Do I need the 93-97? Will they fit the t-block? Could I just change the end of the line to the through-bolt type?
I think I can rig up the parking brake with the old line, but if not, 93-97 for that too?

I don't know about the year range, but so long as you know the sizes you can just go to a parts store and get one.
If you don't know you will want a rubber line by the caliper, (dosen't have to be to long) just make sure it's not tight. That will allow the caliper to move like it is supposed too.
You will also need a new prop vavle or an adjustable prop valve, as disc brakes take more pressure.

You wouldn't be able to mount those lines to the caliper. Check the pics in the following link to see how the flex line mates to the hard line and to the caliper (also take note of the mounting bracket where the two join):

Should you not require braided lines, note that the P/N's for the rubber versions are provided in the above link.
The parking brake, with 90-92 conversions, has been a problem since they're self-adjusting. Discussed in the link below:

Re: What brake lines for drum to disc?
Buy lines for your car, not the LT1 car. You need a hose on the end of each hard line (hence the "requires hose" comment).
Use new FRA8901OM hard lines and 1LE spec lines for a third gen, you're set. Don't forget new banjo bolts and crush washers for the calipers.

Re: What brake lines for drum to disc?
Ok so the hard lines from the t-block to the bracket, and then braided or rubber to the caliper. I understand now.
Seems like it would just be easier to use a braided line from the caliper right to the t-block.
Rubber lines are 25 bucks a peice, the russell braided kit is 75. Makes sense to go braided.
Classicindustries.com-393737 for the brackets (caliper inlet to hard line)
Classic lists the rear hard line as FRA8602, but at finelinesinc.com its FRA89010, whats the difference?
