replacement for a 1970 quadrajet
where is the best place to get a rebuilt carburetor for a all original 1970 corvette? I went to change the fuel filter and found that the fitting that holds the filter is stripped. I want to keep it original if possible.

I would check with Lars first to see it he can repair the threads.

I faced the same situation last year. I hate to give this advice because I will get all sorts of negative comments because everyone on this forum will tell you it's impossible to get a commercially rebuilt carburetor that works properly. I went to Autozone of all places and purchased one for $315.00 13 months ago that I have had zero issues with. My original is in a box under my workbench and eventually I will have it repaired. I paid the $55.00 core charge to keep my original. Just a suggestion and a rather economical one at that.

I have sent an email to lars but have not heard back from him. Would you happen to have a current email addy for him? I sent the email to v8fastcars@msn.com. I see that turn around for Cliffs is 12 months and I want to drive my car as soon as I can. I see that mid america corvette does have rebuilt ones.

I got one from Jegs a JET Preformance, it runs ok but I think it needs to be tweaked a bit. My original is long gone. I have considered buying a proper #7040205 but at $1200 to $1400 I just can't justify that price. But at every swap meet I look at crusty carbs to see if I can find the one that the owner does not know he has the one that I want.

while it's too bad you feel like you have to toss out that disclaimer like with the topic of radiators which is very opinionated and becomes pretty much just a bash and belittle any cats who uses anything other than the token brand type thread qjet threads can go askew pretty quickly too,

Do you know who the rebuilder was? I had a Q-Jet rebuilt by Holley which was a total POS, had to replace the main body, hacked pretty badly. I've heard of others having bad experience with Q-Jets rebuilt by Holley. Based on your experience it seems there ARE some rebuilders who do a decent job. Wondering who did yours....

My "all original" 
1969 had a Q-Jet from a '67 passenger car. I replaced it with a BRAND NEW (date coded 0206 - probably '86) replacement Q-Jet for my application for $750, including freight. It was still in the GM box, shrink-wrapped to the plastic tray. Put in a new accelerator pump. Cliff says the air bleeds are too big and I need to change the jets and metering rods for my rebuild. It still pulled 408 hp / 502 torque on the engine dyno. I will let the next caretaker spend $1500 on a "correct" 7029215 carb that has hopefully been correctly rebuilt. Meanwhile I will enjoy driving the car.

Since you already have the required "all original" carb, you just need to get it repaired properly. Lars Grimsrud can do that and I don't believe his turn-around time is anything like 12 months. Don't know why he hasn't returned your e-mail, but I suspect he didn't receive it...or maybe it came into his junk mail and he discarded it by mistake.
Send him another e-mail to V8FastCars@msn.com and ask if he would repair your carb body. IMO, I would just have him do a proper rebuild on the carb while he's at it. The total charge would likely be less than purchasing any other rebuilt carb outright. This way, you still have the original carb, it will not leak at the inlet threads, and it will be newly rebuilt and properly set up.
What a deal!!!

I can repair the threads correctly. Drop me a note for info. The "rebuilt" carbs from the major parts suppliers are junk - please see my article about this.
