Expert Reply:
I reached out to the manufacturer regarding the end caps for your Retrax cover and unfortunately per the manufacturer the end caps are not available by them selves they are only available if you buy the entire replacement side rail such as the Replacement Side Rails for Retrax XR Series Hard Tonneau Covers T-slot Style # RTT-82383.
These replacement rails work with the following Retrax Models:
RetraxONE XR (T-60383)
PowertraxONE XR (T-70383)
RetraxPRO XR (T-80383)
PowertraxPRO XR (T-90383)
If your Retrax cover is not one of those models, feel free to reach back out to me with what model you have and I can help you find the correct replacement rails.
