3 inch lift in a shorty - advice required please

[Porkeh]

hi guys, i had the plan of throwing a 4 inch lift kit into my shorty but, have decided its probably gonna give me way more attention than i need from the pigs and is pretty complicated and expensive to do it correctly, so ive decided to go 3 inch instead. So my question for the shorty veterans or anyone who knows about shorties and 3 inch lifts in them is what are the main things i will have to lookout for and main parts i will need for it to work hassle free. i did purchase most parts to suit my 4 inch, ill list what i have so far then if anyone would be kind enough to let me know what i need and dont need out of my list that would be much appreciated and also what i need if i dont have it.

Parts i have
- Front and rear tough dog panhard rods
- Hel Extended braieded brake lines (suited for 4"+ lifts though so unsure these will work that well on 3 inch setup)
- 6 inch shocks ( was meant for 4 inch flexi coils and extended bump stops)
- extened bump stops
- drop boxes
- extended lower control arms, (not 100% sure on how much longer they are, parts have been sitting there a while and ive forgotten lol)
- upper extendable control arms
- genuine castor bushes with no offset
- bolt in drop out cones + coil retainers
- tough dog return to center steering dampner
- extended sway bar links

The list above is just off the top of my head atm, will double check when im home and update!

Also my gearbox has already been spaced down 10mm, would that be beneficial to the famous tailshaft issue? or would a space help out too?

Any input to point me in the right direction is more than welcome
cheers alex!
