Jegs mini starter problem

[twoskies]

Good Afternoon All

got a jegs mini starter part #555-10009,

had one i orginally installed January 2018, lasted 6 months, started cranking slow , then not at all

Jegs replaced with the same June of 2019, (no charge, good customer care to deal with every time ive dealt with them)

Went out today , started slow, but its been cold and ive been on call for a week so have not driven truck, went to mall, came back out, no start, only clicks

had a buddy stop and try to jump, no difference, finally got a metal rod and tapped starter, started right up

got home and tried, it did start but slow crank

does not have any binding or noise when regularly starting, sounds like a new vehicle, its usually that quiet

1972 C10, 350/4 bolt, 4 speed stick

anyone used the corvette starter with out any issues,part # if possible, might try that or ill just go back through jegs to replace

Thanks
