1965 GMC 5000 with toro flo

[Winchrig]

Hi guys this is my first time posting on here so I hope I did it right. I have a 1965 GMC 5000 with a toro flo diesel and I’m not sure which one it is, can somebody point me in the right direct for a tag on it or something. Plus the other day when I drove it to town a big oil leak started and I still have to double check but I’m almost positive that it is the rear main seal which doesn’t sound easy to find. If anyone knows a good place to get parts for these it would be greatly appreciated. Thank you!

Interesting truck. Heavy Front Axle with Wide Front Fenders. The size of the Engine will be on a Pad on the front of the engine near the water pump.

Keep us posted on it.

Most likely that truck has a D478 Toroflow. The D351 was very rare, and usually only in 4000 and 4500 series trucks.

Sorry I didn’t get back to this real quick, I’ve been busy on other projects. Tonight I will be checking for the pad on the front of the engine and I will let you guys know what I find.
