Need advice for new rear leafs, stock height to match 1.03 bars.

i have used the oval track springs and if i remember correctly the front half is 1/2" shorter so the extended front mounts were required.They were made in Mexico and both had grinder marks were they were tested for hardness.I was impressed with the ride.
I also have used the espo stock 6 leaf springs. I think they sent me 1" over because the dart sat too high for my liking so I made new front spring mounts to lower the rear to stock height.The ride is good.
