D35 to 8.25

Hey I am going to regear and had some questions I can't find answers for so I thought I would throw out some questions.
First I am still mulling over 4.10 or 4.56 gears but I am definitely going to get rid of my D35 and go to a 8.25 so my question is are the spring perches the same and the yoke the same or are there mods I need to do. Can't seem to find the answers I am looking for because the lift I have on was very specific on if I had a D35 or a 8.25 so I hope I don't have to buy new springs. I know alot of people have done this swap so what do I need to get it done?

d35 pinion is shorter so driveshaft length is an issue and the 8.25 axle tube is slightly bigger so you different u-bolts. the spring mounts are the same.

no you dont need new springs.

Thanks that is a relief.
