There is no hole in the BB to pour anything into the seat tube. I tried getting pb blaster in the keyhole but the post is tight and nothing gets between the post and the tube.

Bummer. I'd still keep squirting some between the post and tube and letting it sit for hours. As many times as it took. I haven't used PB Blaster but I know most of those kinds of products will find their way between stuck parts eventually. After a few long soaking in sessions, if it still doesn't budge, heat that seat post.

 I'll get it out when Im ready to redo the build and am ok with destroying the seat post. Just didnt want to do it now as Im temporarily gonna leave the bike as found other than the forks. Forks should be here tomorrow. Everything is scrubbed and reassembled. The good news on the post is that it has two fluted indents. One on each side so Ill keep spraying in those flutes.

Soooooo I spent ALOT of money on these 26" Landing Gear only to find out when I got them today and went to put them in the frame that Landing Gear steer tube is considerably shorter than the Tange. The LG steer tube is 6&3/8" long for a 5" head tube and the Prodyne has a 5&5/8" headtube so the needed fork has a steer tube that is 6&13/16" long. The LG fork top edge of the steer tube only comes up level with the top bearing. :(

Also as far as the Tange being or not being bent, by looking at this set on Ebay, mine are extremely bent.

Ouch! That really sucks. I’m sure you’ll get it all squared away. Good luck

Sent the fork off today to be straightened but hoping to sell the LG and be able to buy some CBR forks. Decided to go ahead and bolt a stem to the seat post and attached the LG fork to the stem and twisted and the seat post snapped off so now it's back down to a bare frame. Filled the seat tube up with PB Blaster and then filled it with hot water and am letting it soak. It's about six inches into the frame.

48 hours soaking. PB Blaster in seat tube filled to the top. Cut a couple relief slots with a hacksaw down to the seat mast. Dumped out the PB Blaster this morning and stuck the remaining seat post in the bench vice. Clamped it down and started twisting the frame back anf forth and finally POP and I lifted the frame right off the sear post. Frame was greasy feeling from all the penatrant that ran down the frame so I washed the frame with soapy hot water and then went through the whole process again. Two rounds of rubbing compound, two rounds of polishing compound and then two rounds of wax. Nightmare finally over.

Wow...the suspense that was building!  “Is he going to able get the post out or not...?”  I just didn’t know.  Lol.

I’m glad you were able to get it out. It gives me hope that just about any post can get removed without damaging the frame.

Well she's finally done. After much back and forth in my head, I decided to initially go with the "as raced/ as found" combo. I'm a complete sucker for true survivors. I can't say thanks enough to shotgun for the help straightening the fork and farmboy for hooking me up with the exact seat post I needed and Metzone for the hookup on the exact tire I needed.

As I said before, I replaced the tubes, rim strips, seat post, and added a brake cable ( it didn't have one). Everything has been scrubbed and polished (more than once). I also changed the brake lever. Otherwise it is all as it was back in 1981-82.
