Just installed modern shocks on my 30. m.a.c.s_fabrication is ebay seller. I like the gas charged shocks over none.
Big improvement on worn originals. So, why modern? Although I think they are better, it came down to cost. Full set for price of one new original type.
No welding, no drilling and rear mount came be installed using front side longer rear backing plate bolts, so I can go back to original style whenever.
