What was the last year for the production of the 534? Also I had someone tell me that after the 534 was out of production that the 477 was relabled a 475 and continued in production for a few more years. However I have never heard of this and am having a hard time swallowing that tid bit of info about a 475. Any information on this would be greatly appreciated.
1981 was the last year for the 477 and 534. By that time they were available in the C-900 and L-900 only. The 475 was really a 477 just for the F-880, an oddball F series medium duty that was around for a few years in the 70's.
