1971 high lift coil spring - HELP

[caddyman82]

Hey all,
Hoping someone might have some experience with this. I have a 1971 Mustang Coupe with a set of High Lift Coil Springs from JC Whitney installed. They were purchased around 1999 but are no longer sold by JCW and when i've called, they don't have any info about them. I have the original reciept from the previous owner but it doesn't say how much lift. The problem is the shocks went bad and the standard size/oem replacements are too short. They fully extend any time i hit a bump. I could change springs but like the raised look.. I've reached out to KYB shocks to see if they have a shock with the same mounts that is 1" to 2" longer extended. Any other thoughts what I could try?

Original JCW catalog number 87LT8848p
Receipt shows manufacturer part number as: 1007 (but doesn't have any other info.

Interestingly they also sold high lift leaf springs for 64-71 (86LT5620x). Also no info about how much lift.
Hoping someone else might have some knowledge here.
Thanks

So is the problem the shocks are too short? That you can get fixed at the FLAPS if they have a Monroe catalog. I used to find Custom fit shocks by 4 specs: top mount type, bottom mount type, compressed length and extended length. You can get the first two bits of info from the stock shock number on their chart in the back and Then look for what you want for length. Find a counter tech that still thinks he needs to shave every day, and he’ll know what to do. I have seen spindle extensions for the top screw on type, but wondered about their quality,
