Motor plate dust covers- part #1987 & #1988

[R6cowboy]

I'm searching for motor plate dust covers for both my Blue Eagle and SRT. The Traxxas parts lists for both trucks indicate dust cover part #1987. While searching I'm also finding dust cover part #1988, which all have been clear. And the #1987 dust covers have been either white or black.
My question is, are both part #'s physically the same covers, and the only difference between them are the colors?

Well I know when the 272 "Magnum" trans first came out (case with two piece aluminum motor plate/guard) the upgrade kits had the clear lexan cover, I think the subsequent full kit releases switched over to the molded nylon cover. I would think as long as they both have a 19XX prefix, they would both be compatible with the Blue Eagle/SRT style motor plate, with the color being the only difference as a running production change. The clear 1988 would fit but be more appropriate for a period correct early Blue Eagle build.

This is reassuring. After closely looking at many different pictures of the dust covers, that was exactly my assumption. Therefore, ordered two clear #1988 dust covers simply because I prefer the look of clear covers so the pinion & spur are visible.
Really appreciate the response, thanks.
