After looking on the first page, that diff "issue" is all solved now correct in the newer kits?

Also, are blank pistons available anywhere? Or just those "option" parts that are predrilled?

also, do you sell a spring KIT that has all of them? just looking to see if $150 in springs is really the cost to get all of them for a full tuning option by buying at $10/each

and what body is on the truck on the first page?

Thanks so much for all the help
