Traxxas terminal connectors...

[Dandare]

I bought 2 packs of these (male/female inc. in each) Assuming the gold connectors were all the same length i proceeded to solder them up but only 2 of the 4 would 'click' home in the connector blocks. i measured the length of all 4 & found 2 were 19.5mm long & the other 2 to be 20.5mm long, only the longer ones would push home in the block. I opened the 2nd pack i'd bought & found the same ie, 2 x 19.5mm & 2 x 20.5mm. I had to use to longer ones from the 2nd pack to replace the 2 short ones i'd already soldered to complete the job. I now have 4 x 19.5mm gold connectors, which by rights aren't going to work.

I can't find anything in the leaflet regarding different length connectors so either, a) i've done something wrong b) i've been very unlucky & have managed to purchase to seperate packs, both with the same issue !

Any ideas plz ?
