[A/S] Tinnerman Clip ?

["Dan @ Mac" <searchcz@xxxxxxx>]

We've been restoring a 1976 Tradewinds and are now moving into re- 
assembly phase ... and I'm afraid we might run short on the U-shaped  
clips that push on to the wall & overhead panels to lock them into  
their tracks. I'm pretty sure these are called "tinnerman clips" -  
they look like a short ribbon of steel shaped into a U or J shape,  
square back, slightly differing lengths on the two legs, with barbs  
inside to hold the panel and outside to hold the track. (roughly the  
size of a chicklet)

My challenge ... there are about a million different types of  
"tinnerman clips" out there and I'm having a rough time trying to  
sift through them all to find this particular clip. Anyone know a  
supplier, or have any advice, it would be much appreciated. Thanks!
