lokar stuff and ls guys...need advice

[pcmcobra]

I am looking at a few options for linkage to a 4l80e. I know some/most guys that have swapped out there trannies have the problem of dropping down the gear to 1 because of linkage on a 4l60...correct me if I am wrong...
My truck is a th350 3spd. Now I have a 4 speed indicator cluster, give me some ideas on the best way for this. Would the lokar shift linkage setup work for me to go in all gears?

I know I gotta get another tranny dipstick, gonna go with the lokar 36" for the 80...
