long story, any help would be greatly appreciated.

I joined this forum almost two years ago maybe even longer. I own a 69 camaro and a 99 camaro. I was an E-4 at the time not making much money, at the time all i had was my 69 when i blew the tranny. I did not have the money to repair at the time so i stored it. It pretty much stayed there for the next couple years. I did not know much then but i have come a long way since then. Over a year ago i made E-5 and bought a 99 z28 with the intention of fixing up the 69 pro touring style, but i got scared of messing it up and regretting it. So i began modding the 99 and realized i really wanted a twin turbo car. So of course i started buying all the stuff for the 99. I went to a shop and put my money into it and bought alot of stuff. All of this was happening while i was on deployment. I got back and nothing was done. I was angry but the owner was the only one there, he had just recently highered a familiar face in the ls1 community and he was churning out some good work. So i kept faith, but i drove my car around for the next 4 months until i went on my next deployment to drop it off. I am currently on the deployment and he fired the guy and is going bankrupt because he is doing nothing. I have my friends going there this week to pick up all my stuff and car before it is too late. Now i am out at least 12 grand and jack has been done to my car. I am going to take legal action to get my money back, but i am afraid that it is not going to happen, because i am not the only one.........
This really sucks.........
I am going to install all parts for my 99 myself or maybe sell them, but now i have to put my interior back in because i took it all out to get the roll cage put in.
No i am done trying to mod the 99, i feel like quitting, but dammit i want my twin turbo car. I have the turbo kit, and hopefully a certain shop has my short block. I will find out on monday when i get a chance to call them from some random country.
Now i remember seeing i think retro rides used a 4th generation chassis on a 69, i would just want to use the front clip and maybe a quadra link in the back. The reason for that is i bought an aps twin turbo kit for the f-body and it was designed around the second generation bmr k-member. I now want to put this into my 69 and make it a pro-touring beast like i should have done in the first place.
So that is my question, how much work does it take to put a 4th gen front clip on, and would it make the car able to handle good. Or is there an aftermarket company that makes something that i would be able to put a bmr k-member on it. Or would that mess up the front end geometry for the car?

Sorry for the long story guys just had to vent a little. Thanks for any advice tips or help.
