Greetings! Dont know how many of you are from the Southern California area but I figured it cant hurt to ask..... I have my 80' off the frame and all suspension, lines, and other parts removed. Other than the #4 body mounts, the frame looks really good. I am welding on new #4 mounts. I want to send the frame out to have it professionally cleaned and powder coated. Probably a pricey option but I am making this car like new and I hate to leave any stones un-turned. I am having a blast working on the car! Does anyone know of any good shops? Thanks, Tony

Can't help with a shop recommendation, but...watch out when powder-coating some items. The powder coat adds to the dimensions of the part, making it thicker. On a frame, it may not be much of an issue, but if there are any threaded parts on the frame, be sure to chase the threads with a tap before trying to reassemble it. The threaded holes in the front and rear of the frame where the bumper brackets bolt may be the only real problem for your year, but it helps to know about this stuff before trying to figure out why the dad-gum bolts you took out now suddenly won't go back in the same holes!
Just a little info...

I was on another website for old trucks the other day. An owner in Cal. somewhere had just had his chassis media blasted and powder coated there for under $500. If I can find that thread again I will post it.
I found the thread. He used Clovis Powder Coating in Clovis CA. Somewhere near Fresno. As you see, I am no where near CA and I don't know where that is. It was $450 for blasting and powder coating late in '05.
Joel, Thanks for the heads up! I had not realized that powder coating was a thicker process but it makes sense. Great tip on the threads, man that would be a real pain if I dont chase all the holes before trying to re-assemble. Thanks Again. Tony
Thanks for the leg work. Sounds a bit too far away from my area. It would be great if that is the general price! Doesnt sound too bad. Its a lot of time and labor for me to do. I will let everyone know what kind of prices I come up with. Thanks
I did a powder coat on a motorcycle frame several years ago and it came out great. I did all the prep and a friend who own the shop did the coating and finish.
Best advice he gave was to put bolts in every hole to protect the threads and prevent a lot of cleanup having the chase the threads.
Works Great !!! Course there is a few tricks here too.
Make sure all the threads are good first.
Get a bolt several threads longer than needed.
Install till the bolt JUST comes out the threads one or two turns.
After coating, turn the bolt in and out af few times to break the coatings at the holes. Done patiently this will not chip or mar the coating around the holes.
Stand back and admire the perfect job without having to have ten different size taps and thread combinations and making sure you didn't forget one somewhere and have to find that tap again !!!!

Thanx for the tips, Nick!
Which is worse, tho...gathering enough different sized bolts to fill all the holes, or tapping them?!?

Iv'e had Chevys for years and have a 14 X 14 metal box which is full of extra bolts and such. Seems it's allways easier to find it than the right tap with the right thread count and the handle when i want to change sizes.
Tony,
I read that you have your body off the frame while you do the frame restoratio. What did you do with the body...did you build a frame/fixture to set the body on for work and storage? I've got a '71 and need to get the body off the frame for some work and am looking for input. I was planning on building a frame/fixture with wheels that I can roll around. Before I began, I wanted to ask for input...no sense in reinventing the wheel. Any input would be appreciated.
Thanks,
Skip Morehouse
