87 truck V20 front axle

[dc7432]

I have a 87 V20 truck 4x4 and was wondering what standard size axle is for the front end. It's a 10 bolt and I need to order a spindle and summit has a few options. Any other sources for spindles? Thanks

I'd get the numbers from the housing to hopefully nail down manufacture date

Might have been swapped at some point
