Hey Bias-ply guys...sizes??!

[**grumpy**]

Im thinking I want to run bias ply whitewalls on my trk.
I have access to 4 L-78-15s but not sure if those will be too big for the front.

I have 4 really nice plain steel 15" 5x5 wheels. so I know the tires will work on the wheels, but just dont know if thats too big a tire for the front.

My truck has 72 disc and 2 1/2" drop spindles and will be bagged soon.
Rear is 72 12-bolt bagged with 2" blocks.

So if you're rocking bias-plys, show some pics and tell us what the sizes are!

Thanks
