Tie rod end dimensions?

I need to buy a replacement boot, unfortunately I can't find the dimensions anywhere. What I'm looking for is dimensions on the chevy steering tie rod end (@ Pitman Arm). Spicer part number: 401-1195B. If someone has one handy can you measure it up for me? Thanks

I need to order a replacement boot and I am not going to have the TRE off for about 2 days and I need the boots to be there when the TRE is off.

Thanks
