NOS Part# ID, Rare single crimp rear brake line, 68 69 GTO Chevelle GS 442 ??

[1969camarors427]

I have 2 early NOS rear brake flex hoses. These are the hard to find lines that have the single crimp on the fitting instead of the 2 crimps from 1980 and on.
There are 2 different part numbers on the hoses, one is 9747244 which comes up as 1968 GTO 442 GS Tempest Lemans Skylark. This one is 14" long.
The other hose part number is 9743259 which I can find no information on, change up numbers ?? This hose is identical but 1/2" shorter at 13 1/2" long.
Would these hoses also fit 1969 and 1970-72 Chevelle also or was there a difference in the 1968 hose length or the mounting position. All being "A" Bodies.
I also found one listing on ebay showing the same hose was used on a 1969 Camaro with the 14" length.
Stickers still attached with the green stencils on both hoses. (see pictures).
Any help appreciated. Thanks.
