Re: Super Stock Springs Update

[Donald Gallimore <dongallimore@xxxxxxx>]

I did a lot of buy and try effort with my '65 Belvedere trying to get the correct front spring hangers.  The 2" was too much (no pun intended), the factory unit was too short.  I ended up using an A-Body set I found at a swap meet.  They moved the spring perch back about 1".  Note that from what I've read, there is a difference in front spring eye location between the '65 Belvedere's and '65 Coronets.  There is a 1" difference.  The Belvedere is 116" wheelbase and the Coronet 117".  Read that in the Darrell Davis book on the '65 Hemi cars. Anyone got that book handy that could veryify that info and supply the details?

Measured the the frame to spring eye on my cars in the garage.  For the dead stock '65 Satellite, it is 2 3/8".  For the '65 Belvedere with the SS springs and the A-Body front spring hanger, it is 3 1/2".  So, by deduction, it appears the difference is roughly 1" between the stock and SS front spring segment length.  Again, this is a B-Body Plymouth, not a Dodge.

Thanks for the help, and keep the ideas
