something about insulated gloves and snowmobile suit makes it hard to crawl under a car just now
I heard that! We're enjoying a very mild winter here- so far.
The flexplate wouldn't have bolted on (229 is 2-piece RMS, the '90's 4.3L is 1-piece RMS- they have different bolt patterns), so no worries there. The only 4.3L V6 Chev engine that could have used the 229 flexplate is the very first year of the 4.3L- '85.
So as long as the starter nose matches the diameter of the flexplate- and the holes in the block for the correct starter are present and accounted for- you are good to go. In my experience, the only engine that may be a problem is a 229 V6 Chevy, as some or all had only the side by side starter bolt holes for the smaller flexplate from the factory, and on the 229 engine I had experience w/this problem (a '81) was also lacking enough "meat" to drill the offset outer hole.
