How hard is it to convert Auto trans equipted trucks to manual trans setup. Are clutch & brake pedals available? Is hydralic clutch parts still available from GM? Looking at building a late model Sub 4x4 into 1 ton HD tow rig & selling my K5. Can't seem to find a 86-91 manual trans version. Did they make them? 87 K5, D60 & 14FF, 5 sp & NP208 & 383 stroker. Build it Bulletproof and take it fishing!
