'35 Ford Rear Spring

I would like to know the stock distance between the spring mounting points on a stock '35 Ford rear end, from radius rod mount to radius rod mount. I'm mounting a late model rear under a '35 Ford spring and frame and I want a starting point. Thanks!

 

35,36 Ford Rear Spring mounting points are 48 9/16" apart.

 

Thanks HemiDeuce! That will save me alot of time.
