Tom Norris,

I think a look into the R390 -35P TM would list the hardware for you. The 
parts TM had almost all the parts listed with a parts description i.e. bolt, 
8x32x0.75 stainless steel, recessed head, #2philips. 

Lets get the new guy pointed out to the files on the web pages and explain to 
him what a parts manual for the receiver is and how to make use of it.

We never ordered bolts for the receivers. Every ASA shop had a big parts 
cabinet with all kinds of things in it. It was called an ME9 Kit. If you ran out 
of something you ask the supply sergeant to order some. His response was not 
good but someday (30-60 later) a box of 100 would show up and we would dump the 
contents of the box into a drawer in the cabinet.

We would order broken clamps. The spline bolts we ordered by the hundred. I 
would change those out in the IF deck extension shaft clamps and the KC MC knob 
clamps on a whim. Just let my spline wrench slip in one of those and it was 
replaced. The parts were just over there in the drawer and did not even need 
any paper work.

Finding good stainless steel bolts with the proper head style is a bitch. The 
exact length is not real critical. The thread is standard. Most any one can 
cut one off if it is so long as to be offensive.

Put together a kit of every thing and it will still cost more for the mailing 
envelope and postage than the kit contents. Just doing it you could sell a 
bunch. (OK maybe 20 and I would ask Hank for a second opinion on that number.) 
The most useful item would be a large bunch (20) of the 4-40x 1.0 clamp bolts. 
These would not be spline but just a hex key head. Include enough bolts and 
matching nuts to convert all the clamps in the receiver and have some spare. It 
will not take care of the splines in the transformers. But it would help a lot 
of the mechanical problems. Include a clamp for the 1/4 IF deck extension 
shafts, One for the KC MC knob. Look into the parts list and provide one clamp 
with hole diameter for the gear train and cams. A hole bunch of pan head 
6x32x0.375 straight slot bolts for the terminal strips on the rear panel would go a 
long ways. Some 6x32x0.74 Philips for the RF deck cover would also be nice.

Just my quick list.
