engine mount thread/size

[TurboSurge]

Hello I’m getting my swap wrapped up ,but after a long roll and a tree,
My engine mount nuts have been lost. Does anyone know for sure what the nuts are as far as thread count and size?? Needing to get my truck on the road quickly so any advice is much appreciated!!

I'm 98.43% sure they are 1/2 course thread

Get flat washers and I would recommend nylon lock nuts. Factory ones had the flange type nuts

Just for reference, anything going into the motor will be SAE thread. Anything else is generally metric. So, say, your alternator adjustment bracket(on a bull/bricknose) bolts to the engine with 3/8-16, but has a similar metric thread holding it to the alternator.
