Since the PCR was generated by 27-F and 1492-R primers, It is a known fact to use internal primer for sequencing to improve the quality. SO, I realized 907-R primer was used instead of 27-F primer an internal control sequencing primer to sequence the opposite direction of the same gene. That should cover the first part of the sequence (from 27F to 907R) and use the 1492_R to sequence using the opposite direction. So, what to do could be to use BioEdit to reverse complement both 907-R and 1492-R sequences, run pairwise alignment and generate consensus. You may edit a few IUPAC code seen in the consensus, copy the consensus sequence and run BLAST.

Oloyede Joshua Oyekanmi I have a feeling that it is technically wrong to just do a pairwise alignment in that manner when your intention is to assemble reads into a contig. its better you try out assembler tools. you should note the difference between an alignment and an assembly. Although assembly entails alignment, its alignment doesn't contain gaps. it rather attempts to find and merge an overlap without any gap in it. if it is to be lenient it can only allow some few mismatches but strictly no gap. in contrast, pairwise alignment can have gaps and its done to compare evolutionary distances between two different sequences. its so rare when a pair wise alignment can give you a distinct overlap. if you are using bioedit, try the cap assembler application provided with in biodeit. it will attempt to get you a contig of your two reads. i hope it helps https://biology.stackexchange.com/questions/40436/what-is-the-difference-between-sequence-alignment-and-sequence-assembly
